Basically, make sure the int10/VBE initialization calls aren't disabled.

Never heard of that... if it does what it sounds like, are you able to
get radeonfb working?

You'd have to get a backtrace with gdb to see what causes that.

I'm afraid so:

I don't think the card has only 8 MB of video RAM? I suspect this is due
to the memory size register being uninitialized as 0, which causes the
driver to assume it's 8 MB (because there were production M6 cards that
incorrectly reported 0 instead of 8 MB). This indicates that the video
BIOS hasn't initialized the card.
