I'm running a slightly patched NetBSD 1.0 on my ThinkPad 750.
I also have XFree86 3.1.1. installed, and it's using the pccons driver.
I see two strange problems:

1) sometimes when I start up X, I see "ghosts" on my LCD that look
very much like those caused by multipath on a television.  That is,
a dimmed replica of the main image superimposed a few pixels to the
right.   This is using the XF86_SVGA driver.  I've seen this both 
happen and not happen with the same XF86Config file, though it may
depend on whether I start the X server from the console keyboard or 
from a remote xterm.  (it's hard to test because of problem #2)

2) whenever I leave X, the keyboard fails to work.  I've tried retro-fitting
the pccons driver from -current (changing the call to intr_establish back
to the two-argument version, and a couple of other minor changes), and
I get the same result.  I haven't found a way to fix it except to reboot.

I do have the keyboard reset routine commented out (#if 1 changed to
#ifndef TP750) because it doesn't work with my keyboard.

(Hmmm...since the keyboard/mouse share the same hardware, maybe the 
mouse driver is the culprit?)

Suggestions as to how to cure either or both problems will be appreciated.
