mouse doesn't work

[mpx <mpx@casema.net>]

hi dear debian's,

i just installed debian for the first time, and wow, this dselect was
heavy work;-)
now finally everything is done, even x is working well, exceptly the
mouse doesn't move.
i thought it should be a ps/2 one, but didnt work, so i tried out a few
more from the xf86config, till i get to the more exotic ones and left
it. so i changed the default /dev/modem to /dev/tt* but the same
thing...:(

i was wondering if someone experienced the same thing on a
compaq-machine?
i use a compaq armada 1575D
even compaq.com didn't show any useful info

thanx in advance and hope someone has any idea
