Created attachment 141981 [details] .config for the kernel
The following patch[1] should address your problem. This was committed into the mainline tree and is available in gentoo-sources-2.6.24. Can you please test that kernel version and let me know if your warnings disappear?
Which patch? Do you mean the git link??
I tried the git link. The warnings are not completely gone.

Upstream reports that there is a future patch that will fix this: http://lkml.org/lkml/2008/1/26/221 upstream states that this is a harmless warning.
As upstream has indicated that a forthcoming patch will solve this one and the messages are harmless, I am resolving this bug.
