I have used the 10.4.0 kernel on the 10.6.2 system, thinking it would fix the sse3 emu problem (older p4). but still no changes, safari, xcode, mds, QuickLook helper, still use 100%

When I try to install the 10.6.3 updater. its still stuck at "Examining Additional Disks"
I was able to install the 10.6.4 accidentally, but the GMA900 would not work, so I could not go to the desktop.

Has anyone expect me tried the new kernel on the sse2 system? I don't think anything has changed for the sse3 emu since the 10.2.0 kernel. but yet the description says its a rewrite..

Has anyone tried it on an AMD system with sse2 only?
