Glad to hear your system is still working. I was worried this fix won't last long, since I would get a kernel panic if I didn't boot in verbose mode. But I added kernel mach_kernel to the apple.boot.plist, and so far everything is great. Anyway, how did you get sound and sleep to work on your system? Those are the only two issues that are keeping me away from full system functionality. By the way, did you get your SD card reader working yet? I found a kext that works well on Lion. If you need it, just let me know.

I just tried the modified mach_kernel on my system and it fixed the need to use cpus=1 ! My computer is faster than ever, and my geekbench score has doubled from the previous score (although it took longer to finish the benchmark this time). Thank you everyone for all your hard work. (Now, if only I could get sound and sleep working )

Hey scorpioserv, How did you get sleep and sound on your system? I have an HP dv6-1253cl laptop that just had Lion 10.7 installed on it with no dsdt. I have gotten everything to work well except the sound and sleep feature (and the cpus=1 problem, but will try the kernel patch on this thread). I have the same sound card as you and have tried the GenerateCStates and GeneratePStates=yes on the apple.boot.plist. Can you upload the kexts you used to get your sound and sleep working? Or some advice? I will post more systems specs soon,
