Just a small update about our rollback I need to correct. Turns out our problem has been solved by going with the 2.6.20-r10 of the gentoo-sources patched kernel. Although gentoo marks this as unstable for amd64, it's working fine. I've made no other changes than going back a few versions on the kernel and adjusting the .config w/ the same settings.
Tomorrow I'll likely give the next marked stable patched gentoo-sources kernel another try which was 2.6.24-r10 and recheck my configs and try to gather anything else I can gather from it.
