i have a rebranded version of a Aiptek 6000U. from Dick Smith www.dse.co.nz
it seems it acts like a mouse. which is bad, obviously. but good in the fact that it is found.
i use Gentoo Linux, the 2005 release. and i am using the driver which is already installed which seems to be the same one as http://aiptektablet.sourceforge.net/
the ratio the pen can move to the screen is off abit. and there is no sensitivity. but if i move the pen to an area on the tablet like. lift the pen up too high so it cant read. it will jump to the new location. so in that sense it isnt like a mouse :S

root@leviathan ace # dmesg | grep aiptek
drivers/usb/input/aiptek.c: input: Aiptek on usb-0000:00:02.0-1 (event2)
drivers/usb/input/aiptek.c: input: Aiptek using 400 ms programming speed

drivers/usb/input/aiptek.c: Aiptek HyperPen USB Tablet Driver (Linux 2.6.x)

its mounted the device on /dev/input/event2, and uses the aiptek driver.

that says it is indeed aiptek.
