I did precisely that, and didn't notice anything special (du on kernel
source tree) kernel 2.6.32.11, deadline scheduler, 7 drives RAID-6
array, 8GB RAM.
I guess, you're not on this specific openSUSE git version of 2.6.32.11 (e.g.
the preparation for SP1 of SLE11), which, as usual, carries a lot of stuff
from later kernels. The offending patch was included in linux-2.6.33
between -rc4 and -rc5:
