Does anybody know how to set up a Mac Pro to hibernate after a set period of sleep?

This weekend I went away and wanted to cut the power to the desk but not lose my user session so I modified my MP's power management settings by switchting hibernatemode from 3 to 25, set a small standbydelay value and turned everything off when that time had passed.

Safe to say the MP did not like this one bit. Upon my return I spent the evening to revive it which included partial disassembly and a fair amount of cursing. I assume hibernatemode 25 is just not compatible with the system?

These are my (working) power management settings -

Code:
