Andrew,
Could you please queue this one for your next -mm - first attempt was too
eager at complaining - it's ok to have timeout while we probing ports, etc.
so warnings should only be produced if mouse is in active state.
The patch depends on the one you have.

ChangeSet@1.1514, 2004-01-10 23:50:51-05:00, dtor_core@ameritech.net
Input: Change the way timeouts/parity errors are handled:
- Only complain about errors from keyboard controller if mouse
is activated
- Reset packet count to 0 as the next received byte will most
likely be the first byte of a new packet
- If expecting an ACK from the mouse set NACK condition
