Oh, But suspend to disk is slower than ppc sleep function, If we can found the way do nVidia chip wakeup is better.

I has try to port suspend ppc,but not completed, I not family with powerpc assemble, So it's hard to do it.

I has tested you 2.6.1-rc1-ben1 tree, but the rivafb still can't work in my laptop, how can i help you?

bad news. I heard other guys do Broadcom 4301 for linux with 
reverse-engineering. The Airport Extme is 4306? If the project has
