If you can boot DSR mode OK but not normally, then AD corruption
would certainly seem to be the culprit. (Otherwise that would seem
to be a problem with the hardware enumeration.)
If an in-place upgrade reinstall doesn't fix it, then you can
try repairing the AD database:
http://support.microsoft.com/?id=258062
or using esentutl as a last resort if that doesn't work.
Not much past that point other than an older backup and/or rebuilding the
domain by hand.
