Here it is for us lowly non tsc syncing laptop bios's.. VoodooTSCSync for Snow..
This is for a core2duo only.. If you have issues w/ more than 2 cores check the Info.plist and the IOCPUNumber that the kext will match on.
Special thanks go out to turbo for the inspiration; Kabyl & Superhai for the plist power, and mackerintel for all the hugs.
@Removed the locking / thread count code. This was causing kps' on > 2 cpus.
This code is availble at: http://forge.voodooprojects.org/p/voodootscsync/
