I have observed some odd behavior when X display becomes garbled if USB
stack is loaded and USB keyboard is attached after user has logged into
X desktop (Gnome in my case). I am setting MODE_280 (1024x768x32) in
rc.conf using 'allscreens_flags'.

I have been playing with it a bit and found out that I can achieve the
same result by doing 'vidcontrol MODE_280 < /dev/ttyv8 > /dev/ttyv8'
after logging into Gnome. And ttyv8 is the terminal, occupied by X
display. Restarting X server cures the problem.

Neither original scenario, nor the second one are very likely, so I do
not know whether it is much of a problem.

I am running -CURRENT from May 14th, video chipset is S3 ProSavage.

Please, let me know if there is any additional information that I can
provide.
