I wouldn't rule out hardware troubles despite other systems
functioning properly. Unless you've done extensive comparison testing,
it could just be bad luck causing it to show up under debian...
But to start on the software side:
1) do you have older kernels lying aroudn in /boot that you could
use to see if it's a kernel issue?
2) try removing the nvidia module for a while and use either nv or
vesa just to rule that out.
3) give us more info: at what point during the boot does it fail?
can ssh into the box when it "freezes" or are you completely
locked out? caps-lock, num-lock working?
4) read up on alt-sysrq key sequences (google works here) so that
if you have to reboot you can do so cleanly by synching the disks
first.
