Binary package hint: linux-image-powerpc

After a Jaunty sync of c. 18:00 UTC 2009-03-19, the new linux-
image-2.6.28-5-powerpc kernel has a problem with the kernel drm module,
resulting in:

* No 3D video acceleration;

* Kernel log messages like:
Mar 19 18:29:41 tigger kernel: [   50.696676] agpgart-uninorth 0000:00:0b.0: putting AGP V2 device into 4x mode
Mar 19 18:29:41 tigger kernel: [   50.696694] radeonfb 0000:00:10.0: putting AGP V2 device into 4x mode

Mar 19 18:29:42 tigger kernel: [   51.052748] __ioremap(): phys addr 0x101000 is RAM lr e2da9d5c
Mar 19 18:29:42 tigger kernel: [   51.052754] __ioremap(): phys addr 0x102000 is RAM lr e2da9d5c
Mar 19 18:29:42 tigger kernel: [   51.052762] [drm:radeon_do_init_cp] *ERROR* could not find ioremap agp regions!
 
Rebooting into  2.6.28-4-powerpc (or pretty much any previous kernel) results in a working system again, no log messages and working 3D. This is newly introduced in 2.6.28-5-powerpc.
