Same comments. It took me a while to figure the logic out, which I end
up agreeing with but the code is pretty obfuscated ... And yes, patch 7
seems to improve things, but then, that makes reading the patch itself
nearly impossible :-) I ended up patching the file and -then- reading
it.

I tried the whole thing on various powerbooks, along with some patches
I'm about to send for radeonfb, atyfb and aty128fb to make them properly
call pci_save_state() before they hand-change the D state, and things
appear to be working fine. (well, appart from some unrelated problems
leading to some might_sleep() hits but as I said, they are unrelated to
this series)

I need a couple more tests of the fbdev patches on some machine variants
and once done, I'll post them out. Hopefully tonight.

Cheers,
Ben.
