G5's JetFighter mode solved ? -need testers!

[Andrew]

I got someone on the forum: 
http://www.yellowdog-board.com/viewtopic.php?p=1646#1646
who upgraded the kernel via yum to 2.6.9  and applied this patch
afterward: 

http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.10-rc3-bk5.gz


He said his twin 1.8g G5 is now as silent as it should be!
Anyone to confirm this is actually working?
