Comment # 3 on bug 76475 from 
Unfortunately the VBIOS from the PCIROM is often the wrong one. The data here
is the x86 opcodes instead of the vbios opocdes. And as you observed, we now
consider unknown opcodes an error. (The init tables need to be run on e.g.
resume, and if it's a secondary card, on load as well.)

An mmiotrace of the blob loading would potentially be helpful, you can send one
(compressed... xz -9 works well) to mmio.dumps@gmail.com.

Can you provide a bit more info about this system? Is it an optimus setup?
Could you provide an acpidump?
