Ok, so after some tests here on what appear to the the exact same
machine...

I did the commit specifically to -fix- a regression due to upstream
changes, ie, for me it doesn't work without that commit. That is very
weird.

In fact, I just tried also with AGP and DRM enabled with X wobbly
windows etc... and it's working just fine.

I know that the early resume hack I have in there for powerbooks might
be a bit fishy, so please try without it (according to my previous email
on that matter).

Please let me know if that makes a difference.

Cheers,
Ben.
