Ok, thanks for letting me know. For some reason, the gmux isn't working
on the latest MacBook Pro so I can't get the vga switched to the Intel
PCI device. Rumor has it the osx tool at
http://codykrieger.com/gfxCardStatus will switch into the Intel chip
until the laptop is hard powered off, so it is possible, just need to
figure out how to make the hardware do the switch...
