Yes, I've had sufficient crashes in the last hour to confirm that.
The manual is correct - the virtual desktop depends on the maximum
resolution specified in the Modes line.
BUT, shutting down the X server is not enough - you have to reboot for
the change to take effect. (!)
Incidentally, I'll be surprised if I get to finish this email. The
machine has been crashing within seconds of starting X. I've had about
8 crashes in the last hour - again, one so bad I had to pull the power
cord to power off the machine.
And it looks like restricting the desktop area to 1280x1024 made the
crashes far more frequent. Until I reset it to 1600x1200, the longest
it stayed up after starting X was about 10 seconds.
All very weird.
