Thanks as always for a quick help.

With those two patches, your fixup message appears in the boot
log 6 times (is it expected?).  The monitor does not go blank
anymore; it safely defaults to CRTCNumber 0.  Overall, it is as
if I am using your nvidiafb driver without nvidia-i2c ;-).

Boot time kernel message is attached here.
