I only just committed this, but the changes compared with -r3 are minimal, and we really need to move away from the ancient but stable 0.7-r2 now, so please test (careful with overclocking - maybe test underclocking instead) and mark stable =media-video/nvclock-0.8_beta4-r4
amd64/x86 stable
ppc stable, bug fixed (there is even a warning when used on a laptop :))
