64 bit update: sleep / shutdown / restart / audio / powermanagement all ok.
Changed the bootloader to asereBLN 1.1.9 and edited the DSDT for the i7 930 processor's -c and -p states with native power management in OSX - thanks to the guys at
insanelymac. Only running fakesmc in /extra along with IOAHCIBlockStorageInjector for orange icons and LegacyHDA for audio. All other fixes are in DSDT with the bootoader handling sleep and shutdown. This means all kexts are both 32 and 64 bit compatible now.
Edit the boot.plist with kernel flag "arch=x86_64" and setting 64 bit HPET in BIOS and a quick reboot using
this tool to check so we are good to go:

After running prime95 the temps only reach the high 78-79C mark, this is after maxing all four (+four virtual) cores for 11 mins at 4.01GHz:

This machine can run at 4.3GHz but I feel better with myself just throttling it back to 4.0 for daily use. In fact the default of 2.83GHz is so good I will probably keep it there for the near silent and cold temps it generates and have a BIOS preset for the faster speed selectable on startup when I need to crank out some video work in Handbrake or FCP.
