FWIW, this will be fixed when:
1) the debian udev package stops blacklisting all video drivers (should
happen soon, it should only keep a blacklist for fb drivers)
2) the debian kernel either switches radeon kms on by default (won't
happen before squeeze), or removes the ifdef CONFIG_DRM_RADEON_KMS from
radeon.ko's pci device table, as was done for i915.

This will allow udev to load radeon at boot automatically.

Pauli's patch sounds like a good idea regardless, though.

Cheers,
Julien
