Xorg does not start. This is on a 10.0-STABLE machine, i.e. new xorg is
enabled by default. Ports are up-to-date.

Trying to launch X with startx fails.

1) It displays:

failed to set mtrr: Invalid argument
Segmentation fault at address 0xc04cc6adc

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

2) And it produces the following messages on the console:

Jul  5 17:01:25 graf kernel: sysmouse: unknown ioctl: t:40007413
Jul  5 17:01:25 graf kernel: sysmouse: unknown ioctl: t:40007413

Jul  5 17:01:25 graf kernel: pid 38406 (Xorg), uid 0: exited on signal 6


3) And the tail of /var/log/Xorg.0.log is:

This is reproducible, and I can give any other details if needed.

How-To-Repeat:
Just run startx. My ~/.xinitrc contains "exec startkde", but it does'nt
	matter.

Fix:
N/A.
