I ran the compile without the P5E patch which resulted in numerous errors (just to see what the patch would do). I applied the patch and all but one disappeared and it was resolved with "fix errors".
The system seems stable and running well. The only items I can not use at the moment are the built in firewire and the third party SATA. I have no need for either at the moment, but may dig into it when time permits.
The DSDT tool is pretty amazing and has all the patches included in a directory. The use was also almost trivial. With the hacking and tweaking, I think I will be able to use the current setup for a while before investing in a new MB and chip. Donation made.
