It seems there is a bug report about the m64B video card not waking up
after a powering down, a problem that only occurs when dtlogin is
disabled. There is also a patch, 105362-10 fixes the problem.
My machine had 105362-8 installed, obviously this didn't.

I installed the latest patch, and everything wakes up perfectly.

Thanks folks,
