Without AGP support radeondrm(4) does not work on my G5. The machine
freezes when X starts and it's impossible to debug.
So I'd like to enable agp(4) in GENERIC again... but leaving it disable
for Uninorth (G4) machines. On such machines w/ AGP enabled the GPU locks
up and then the driver disable acceleration completely.
ok?
