I'm using UEFI and the blob every day without issue. However, that is 
with an add-in card. It's possible that X11 or the nVidia driver is 
trying to reinitialize the card through the (potentially non-existant) 
video BIOS, which fails. Is there any option like "NoInt10" you can turn 
on in X configuration?
