This just means MediaQ is either not present at the shown physical
addresses, or the MediaQ chip was powered off. A friend had the same
problem on Rover PC P5+ because of the line "GPCR0=0xffffffff" in
machine initialization. One of the first 32 GPIOs somehow powered off
MediaQ or something like that.

It's strange because it must be enabled from WinCE. It means either you
use an old CVS with that GPCR0 line, or MediaQ is somehow powered off
during machine initialization. Alas, I don't know how to get it to work
since I don't have any datasheets on mq1178. From register dumps I can
see just that it is very similar to mediaQ 1132, but I also see there
are differences.
