DRM fails to initialize on PowerPC with Ubuntu kernel 2.6.28-5-powerpc, based on 2.6.28.1 (the 2.6.28-4-powerpc, based on 2.6.28, worked fine).
[drm:radeon_do_init_cp] *ERROR* could not find ioremap agp regions!
Unlike the problem with 2.6.29 reported earlier (http://bugzilla.kernel.org/show_bug.cgi?id=12441), "nopat" does not help.
The original reporters will also try newer kernels or build newer drm modules, but the reduced support for PowerPC in Ubuntu makes it more challenging.
