Hi,
CONFIG_X86_PAT is not set my 2.6.30 (that's my best knowledge; I looked
at .config file in the build directory made by kpkg). Adding nopat boot
option has no effect with neither local 2.6.30-rc3, nor 2.6.30-rc5 from
repository.
The firmware messages are like this (firmware-linux is installed):

Is CONFIG_X86_PAT set in your own 2.6.30 ?
What if you disable it, for instance by passing "nopat" on the kernel
command line?
Note that when firmware-linux is needed, it should be said pretty
clearly in the kernel log.
