nopat is useless if PAT is not enabled.

The official 2.6.30 kernel contains the r600 firmware, it just works.

Debian's kernels exclude firmwares, that's why firmware-linux is needed.
But firmware-linux hasn't been updated for 2.6.30 yet, so the r600
firmware is missing.

You should either keep your own 2.6.30 kernel, or find an updated
firmware-linux containing r600 (maybe the kernel guys have an
experimental package).
