This bug is still present in r7, the patch works great though - thanks!

Not in r8 or r9 either.  Is anyone going to do something with this or will it end up going the same way as http://bugs.gentoo.org/show_bug.cgi?id=47302?

I'll roll another kernel package tomorrow with this patch in it.

Fixed in 2.6.7-r10, thanks for prodding me, I needed it :)
