I was able to successfully apply the hrt6 patch to a 2.6.22 kernel. Unfortunately it doesn't patch cleanly against 2.6.22.6. Nonetheless, I must say that the difference is amazing. My current powertop numbers are below. Even though there are an annoying number of libata interrupts on a normal workload (web browsing and such) the processor has had an avg residency in C4 > 50%. I also have attached my original numbers (at bottom) and data after disabling DRI. Thanks again everyone for the help!
