Thanks for this information, I missed this (as well as the merged SATA 
fix) since it isn't yet at the git mirrors.

What's "-git" here? I just now pulled

git://git2.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

and it's not there.

Otherwise, patch confirmed to work by me as well.

Cheers,
Rene

Perhaps not mirrored out yet, I pulled it from master/hera some hours
ago though. The top of Linus' tree is
ec8acb6904fabb8e741f741ec99bb1c18f2b3dee, which is the commit with that
patch.
