hmm, i can see the problem:

root at grml ~ # hwinfo --monitor

With that info it's not possible to know that 1280x1024 at 60Hz should be used i 
guess. This values from hwinfo end up in the xorg.conf and the tft compains.

Well yeah, this does remove the entry.

But there still is the fact that both usb and ps/2 mice and propably all other 
mice too are accessed by /dev/input/mice so doubt that a xorg.conf should be 
created that put a pointer on the same device more than once.

Actually i'm quite confused now, because i just found out that if i do a cat 
on /dev/input/psaux and /dev/input/mouse0 and /dev/input/mice i always get 
data, no matter if i connect the mouse on ps/2 or usb.
I actually didn't expect to get data on psaux when i plug in on usb!

Really weird...
