Comment:
I can confirm that I've got the exact same problem.  X tries to start,
the screen flashes some horizontal lines and then I'm left at a black
screen w/ an "_" in the upper left hand side.  Unable to switch to any
other tty and must hard power off or log in via SSH to shut down
cleanly.

Using kernel 2.6.15-15-686
IBM Thinkpad T21

Thanks!
