I think this is an imcompatibility between StrongARM based machines and
the new PXA ones. They have a different UART :(
This causes problems with the "old" keyboard modules since they do
direct hardware IMHO access to the UART. This will fail on the PXA.

I am working on getting my userspace kbdd to run on PXA but I still
could need a hand on getting the keyboard table mapping right - I still
cannot get ALT-GR to funktion :( For english or US keyboards they should
plain work fine though...
