Hello Rob,
Hello Darren,

The keyboard and mouse issue still exists in the latest git kernel.

Here are the logs:

- http://www.xenosoft.de/dmesg_FSL_P5040_Void_PPC.txt
- http://www.xenosoft.de/dmesg_FSL_P5040_MintPPC.txt
- http://www.xenosoft.de/dmesg_FSL_P5040_Void_PPC_with_Robs_patch.txt

Thanks,
Christian
