4d wheel mouse - scroll wheel no worky
 

I'm running Gentoo, and I can't seem to get my spiffy 4D scroll wheel mouse thingy to work right.

I added the

Option "ZAxisMapping" "4 5"

and changed from Auto to

Option "Protocol" "IMPS/2"

to xorg.conf, but the scroll wheel still doesn't work.

I looked around on LQ for a while, and tried ZAxisMapping to 4 5 6 7, but that didn't help.
