Nope, works fine if on

I have a similar problem with a 2940AU, after a warm boot the video won't come
back on. The machine initializes the SCSI bios (or appears to judging from the
drive light), but won't boot into an OS. The reset button then correctly
starts the machine. Replacing the 2940 with a 1540 fixes the problem (or
rather, replacing the 1540 with the 2940AU introduced it). The problem is
very incidental and not limited to Linux.

Don't think this will help.
