Not really. XFree doesn't know or care about radeonfb, it only ever=20
makes a difference if you want to use the wsfb driver ( read=20
unaccelerated, dumb but more or less hardware-independent framebuffer=20
driver for XFree )

Because radeonfb attached where vga would attach. They can't both muck=20=
around with the same device at the same time. Only this time radeonfb=20
aborted while attaching so vga didn't get its chance.

This is strange...

Indeed it does:

So that's why your video BIOS can't be mapped - no sane address in the=20=
Not sure why radeonfb would insist on trying to map it even without=20
RADEON_BIOS_INIT though, it shouldn't really need it.
I'll have a look at the driver, this shouldn't happen when it's not=20
going to use the BIOS.
