How are you starting xfce4?What's your .xinitrc look like?
Figured it was, wikipedia said it was IA32, so maybe we need to make it i686 so there's no question.
I would just try any/all of the xf86-input-wacom, xf86-input-acecad, xf86-input-aiptek. Then you need the xvxbd to use your virtual keyboard. Using the unit under X, is the only way you'll be able to use it.
Chrooting is probably what you're looking for.
If you have a broadfailure card, you will probably need broadcom-wl-pf-core2.
Does your user have access to the optical group?
I ls in a xfce terminal emulator and abruptly in the middle of listing files it quits and pressing any key returns to the prompt. No use of ls | less or anything like that. Anybody else notice this?
Have you restarted nfsd?
