Package: linux-2.6
Version: 2.6.32-10
Severity: important

Hi,

the sid kernel has radeonfb builtin on some archs:
debian/config/powerpc/config:CONFIG_FB_RADEON=y
debian/config/sparc/config:CONFIG_FB_RADEON=y

This is likely to conflict with the fb provided by the radeon drm driver
with kms.  Maybe they can be made =m instead?

Cheers,
Julien

When you enable KMS, the DRM driver is a framebuffer driver.  You are
asking for two framebuffer drivers to handle the same hardware, which is
of course impossible.

Which says exactly what I just told you (comment 7).
