Is there anything interesting in your Xorg setup? My relevant xorg.conf sections
look like this:
Section "Device"
Identifier "truei810"
Driver "i810"
VideoRam 131072
# Insert Clocks lines here if appropriate
EndSection
Section "Screen"
Identifier "Screen 1"
Device "truei810"
Monitor "glare"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x800"
ViewPort 0 0
EndSubsection
EndSection

No. It doesn't show up in the process list, so I assume it exits with an error
right away.

There is no core file. However, Xorg.0.log shows the following:
Error in I830WaitLpRing(), now is 551900, start is 549899
pgetbl_ctl: 0x3ffc0001 pgetbl_err: 0x0

FatalError re-entered, aborting

Does that "space" line indicate that I'm running out of shared memory? I removed
the VideoRam setting in xorg.conf but this didn't help either.

True. I tried to reproduce the problem using a Linux live CD, but I couldn't get
one that plays mpg or wmv files. This would have told me whether it is specific
to FreeBSD.

I can indeed log in blindly. When running "who" from a remote login the
additional logins show up. Unfortunately vidcontrol doesn't help. All that ever
happened was that the screen went from all white to all black.
