Seth,
[CC'd people, sorry we exchanged a few emails with Seth outside of the
lists, I passed him the acpi tables and here are gmux dumps]
Allright. thanks for gmux-dump. There seems to be progress, as I can see
the gmux dumps for the nividia-selected and intel-selected are clearly
different (I did it twice to be sure, it checks out).
The 2 dumps are at
http://maumae.net/retina/gmux-dump_intel.dat
and
http://maumae.net/retina/gmux-dump_nvidia_only.dat
I hope you'll be able to get something from these.

Seth,
I've put the acpi table dump in http://maumae.net/retina/acpi_tables.tgz
The ACPI stuff for the gmux looks exactly the same as for the machine
I've got. The I/O range is still 0x700 to 0x7ff.
As far as the mem dump, I've done it but can not see any difference
(between case where one or the other graphic card are selected) in
the first 3000 bytes. Not sure I'm doing that well though. I'm just
dd'ing /dev/mem with
dd bs=1000 count=3 if=/dev/mem of=some_file
Am I addressing the right memory or is the switch going to be (or
likely to be) somewhere else?
That's going to access sytem memory, not the I/O space for the gmux. Try
the attached instead. It's going to output the raw binary, so if you
want to view the output do something like
gmux-dump | xxd -g1
