You shouldn't get a panic on AppleTyMCEDriver if you have enabled native power management in your DSDT.
Thanks to dood and WinstonAce's posts I have enabled audio by editing the DSDT file I found for the X58A-UD7 board along with LegacyHDA enabler, this works fine on my X58A-UD5 now.
Needed to disable AppleTyMCEdriver as it KP'd on startup with it enabled which probably means there is something not quite right with the power management?
Anyway here's my patched DSDT.aml for the X58A-UD5 board if it helps.
See post 1, and item 9 in particular.
Having MacPro4,1 in your smbios doesn't cause any kexts to load, but if your MB isn't Nehalem based like the GA-X58A and GA-EX58, that kext will cause a panic.
if you have the macpro 4.1 in your smbiosplist the os will load this kext to add some more features, but it panics on hacs. delete this kext or change the name in smbios
