Indeed. So the "working" state is to not run the VBIOS. Something=
 in there is
upsetting matters (normally running the VBIOS a second time doesn't hurt
anything, it's just pointless work and can cause a flicker). Assuming that
disabling vesafb doesn't help (the way those legacy interfaces are implemen=
ted
can be pretty brittle), please include

(a) /sys/kernel/debug/dri/0/vbios.rom (from any boot)
(b) nouveau.debug=3Ddebug,bios=3Dtrace output from a *broken* kernel boot

Ideally that should provide some further things to look at.
