The following patch provides AGP support from the AMD AGP driver for the
AMD 761. I don't have an AMD 761 and I had to look the PCI ID up, so I
need some confirmation this works. Despite this, it should.

Please test and let me know so I can forward it off. Against
2.4.10-pre9, but should apply to Alan's tree and 2.4.9.

   This option gives you AGP support for the GLX component of the

+ XFree86 4.x on AMD Irongate and 761 chipsets.

   For the moment, you should probably say N, unless you want to test
   the GLX component for XFree86 3.3.6, which can be downloaded from
