No video on Vista 64 startup

ATI AIW X1900 Radeon (multi-booting courtesy of EasyBCD). To put the
matter as quickly as possible, all four systems (Vista 32, Vista 64,
XP, and Ubuntu) have been happily coexisting for a long time. I
haven't used Vista 64 for about 10 days and went in to do some work on
it this morning. To my surprise, the video disappeared immediately
after the green startup wait indicator. Eventually, after about the
usual amount of time and hard disk activity, the startup sound came on
but absolutely no video.
I restored my full backup of the Vista 64 partition from last Sunday—
same problem!
I went in on safe mode but it is impossible to change video settings
or install new drivers in safe mode so that was a dead end.
I tried the repair utility that comes with Vista but it could find no
problem with startup.
My working hypothesis is that something has gone wrong with the video
drivers although that may not be the case. Even if it were, I can
think of no way of fixing it short of completely rebuilding the Vista
64 system checked desperately do not want to do!
Does anyone have any ideas on how to get out of this mess?
