Subject: [PATCH] make i810_audio mmio aware/support for >2 codecs

patch-2.4.20-pre1-ac1-ac97_codec-4codecs:
-cosmetics (report about primary and secondary codec
expanded for tertiary codec)

patch-2.4.20-pre1-ac1-i810_audio-mmio-step-1:
-mmio for accessing the AC97 with ICH4
-workaround for a bug on the Intel D845GBV mother board:
Board reports a tertiary codec while it is
accessed as a primary codec. Maybe IO/MMIO space ordering
is consecutive instead of ID based???

Don't know how to automatically work around this bug,
so for now there is a module option "d845gbv_bug=1"
(try setting this option if your log says
"Primary codec not ready."
but you are sure, you have a builtin codec)


TODO:
-access the bus master operations via mmio, too
