radeonfb: Please enable support for X850XT

[Elimar Riesebieter <riesebie@lxtec.de>]

Hi gents,

I've built in a new graphic adapter. DRI and r300 works well.

Xorg.0.log:
(--) RADEON(0): Chipset: "ATI Radeon X850 XT (R480) (AGP)" (ChipID = 0x4b49)

lspci:

There was a patch which looked like enabling this card:

http://marc.info/?l=linux-fbdev-devel&m=116768377303703&w=2

but didn't went into mainline. The patch doesn't apply to recent kernels. So
could you please tell me how support for the X850XT (AGP) canbe applied?

I've tried:
