Argh missed that one. Is that a bug or a feature? I find it strange that 
the sanity checks are vastly different for both methods.
And it still doesn't explain why mapping the bios failed with 6.8.2 but 
"succeeds" with 7.1.

Anyway, here's a new patch which should hopefully be more correct. If 
that still doesn't rule out the bios as not being x86 video bios I don't 
know what could be done (it should be the same test as radeonfb uses, 
which does figure out it's OF after all).
