shows a black screen. This is because the Radeon driver relies on BIOS
for everything and the BIOS part that is meant to be used by the
driver is obviously bogus on many boards, especially ones with early
Radeon IGP chipset.
Note that the Radeon driver is not in the non-free section of the
Debian archive but there is almost no hardware on which it would work
without a non-free firmware blob and non-free BIOS blob.
