>Description:
It is said, that currently neither FreeBSD's DRM nor XFree 4.3.0 doesn't support Radeon 9200. As I can succesfully launch XFree86 on my Radeon 9200 with forcing ChipID to 0x4967 or similar, I tried the same thing with FreeBSD's DRM. It works, it renders OpenGL stuff, I have tested it with many OpenGL programs -- no panics, no errors, no coredumps. 
>How-To-Repeat:
Get a system with ATI Radeon 9200 card

      kldload radeon

dmesg will output nothing. This means the card is not supported.

Try that after applying the patch & recompiling kernel modules.
