i think i already replied to that thread asking you if you (mattp) could give me a detailed walkthrough because when I do ndiswrapper -l for lsbcmnds.inf it says driver present, hardware NOT present. You got it to detect your hardware. Explain this mattp. Thanks.

did you do ndiswrapper -d (PCI:ID)? I believe you have to bind it to a pci id. do a lspci and get the xx:xx.xx number to the card, then lspci -n and get the xxxx:xxxx number and ndiswrapper -d xxxx:xxxx
then do ndiswrapper -l is hardware present now?

this is something I'll definitely try. I haven't tried lspci yet. Thanks

Guys...looks like my card in not being detected in /sbin/lspci. Does that my I have to run some script like rc.wireless to detect the hardware address of the card? Here's my lspci:

00:00.0 Host bridge: ATI Technologies Inc: Unknown device cab3 (rev 05)
00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M]
00:13.0 USB Controller: ATI Technologies Inc: Unknown device 4347 (rev 01)
00:13.1 USB Controller: ATI Technologies Inc: Unknown device 4348 (rev 01)
00:13.2 USB Controller: ATI Technologies Inc: Unknown device 4345 (rev 01)
00:14.0 SMBus: ATI Technologies Inc ATI SMBus (rev 18)
00:14.1 IDE interface: ATI Technologies Inc: Unknown device 4349
00:14.3 ISA bridge: ATI Technologies Inc: Unknown device 434c
00:14.4 PCI bridge: ATI Technologies Inc: Unknown device 4342
00:14.5 Multimedia audio controller: ATI Technologies Inc SoundMAX Integrated Digital Audio
00:14.6 Modem: ATI Technologies Inc: Unknown device 434d (rev 01)
01:05.0 VGA compatible controller: ATI Technologies Inc: Unknown device 4437
02:06.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus Controller (rev 02)
02:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

now lspci -n look for this number: 02:07.0

It will look something similar to:

00:07.3 Class 0680: 8086:7113 (rev 02)
00:08.0 Class 0401: 125d:1978 (rev 10)
00:09.0 Class 0780: 11c1:0449 (rev 01)
01:00.0 Class 0300: 1002:4c4d (rev 64)
02:00.0 Class 0200: -->168c:001a<-- (rev 01)

***Only a sample, Its actually part of the lspci -n on my computer.
The --> <-- indicate the number needed.
ndiswrapper -d (->yournumberxhere<-)
then: modprobe ndiswrapper

I don't think that address is my card...That's my ethernet port....I'm looking for the hwaddr of the linksys card...which I think has the hwaddr 0012172B04C8

i dunno if this helps, but when the it starts rc.pcmcia it says

probing for PCIC: edit /etc/rc.d/rc.pcmcia

Is rc.pcmcia not detecting the card?

Does anyone think I have to disable my ethernet port namely the RealTek, which reads in as a PCI IRQ inorder to enable the pcmcia card Linksys which would also fall under the pci IRQ in /sbin/lspci?

no you should't have to

USE b43-fwcutter-011 !!!!!

Info at linuxwireless.org/en/users/Drivers/b43#supported

After following their instructions on installation
DO:
Reboot

Once linux has started up you will finally see that your link LED is on. IT FINALLY WORKS!
Then configure your network settings, ifconfig wlan0 up, yada yada you know the deal. Follow:
alien.slackbook.org/dokuwiki/doku.php?id=slackware:network

I know this post is almost 4 years old and that b43-fwcutter wasn't released yet, but I had this same problem with not being able to get ndiswrapper to work. Google searching everything to do with WPC54Gs and linux, only to find posts about ndiswrapper which never worked for me. b43 also works with other broadcom chipsets and linuxwireless.org has a'lot of other drivers for other chipsets.
Finally I can say this is resolved and that other people that stumble upon this post will get theirs to work as well!

thank you, I just want to confirm I got this working, too.
slackware 13, b43 cutter, the slackware networking guide, and these modprobe codes above.
