Hi, I got almost the same spec as above only an ATI Mobility 4530 Video and a Intel WiFi 1000.
For the last 2,5 weeks I'm trying to run OS X 10.6.2 Intel/AMD from Hazerd (with the final patch) on my HP DV 7-2206ed.
I got almost everything working except the CPU
I MUST set in de kernel boot flag cpus=1 or otherwise I get a KP.
The lappy has a InsydeH2O v3.5 BIOS where I can't change ANYTHING (just time & date).
I found out that when I don't use the cpus=1 the KP is happening at the moment that ACPI: System State (S3) is set.
I tried several distro's, boot flags, DSDT-patches (with a lot of warnings) etc. etc.
Hopefully someone can help me to solve this annoying issue.

CPU:Intel® Core™2 Duo Processor T660/2,2 GHz , Level 2 cache 2 MB
