That seems to be a firmware bug on the Pegasos, but there is a
workaround for it since Linux 2.6.35.

At a guess, this may be fixed by a change in Linux 3.0-rc1:

commit 2c78027a62ea38585da1ff944afdc6146335cb7c
Author: Gabriel Paubert <paubert@iram.es>

    powerpc: Fix for Pegasos keyboard and mouse

This refers to a change made in Linux 2.6.36.

Please can you test Linux 3.0-rc3, currently available in experimental?

Ben.
