Re: [PATCH] radeonfb for kernel-2.4.18-pre1

[Michael Clark <michael@metaparadigm.com>]

The patch below is just a hack to get the driver to compile.

I've had success with the patch in the message referenced below which is
from the driver maintainer. It fixes the compile problem in a cleaner manner
by adding the required defines to the radeon.h header file.

BTW - Also, here is my patch to radeonfb to detect panel geometry using
radeon BIOS registers on Radeon Mobility M6 chipset.

   http://gort.metaparadigm.com/radeonfb/radeon-bios-dfpinfo-2.patch

radeonfb still needs DDC detection added for x86 (use OF on PPC to get EDID
info), although the BIOS detection is still required as not all panels
support DDC (such as the LCD panel in my laptop).
