Apologies for the Spam, but I made a lot of progress on the below: Built hp-agp into the kernel, not a module Enabled the fbcon module in the Kernel config Forceload fbcon module at boot Set AGP mode to 2 and allowed KMS on
This got me a black screen in the terminal (some sort of unsupported text mode?) but starting X I can see with KMS enabled I get no AGP bind errors and no DRM panics. GLXGears/Info confirm DRI and HW acceleration with R300 working and no corruption! GLXgears is putting out 1925fps. Now just need to fix the terminal mode! Alan On 09/18/11 00:38, A.
