Ah, okay.  I couldn't find anything about MFGPTs in the available
source, but I did find the following:

http://article.gmane.org/gmane.linux.distributions.voyage.general/1824

It would appear that something between 0.90 and 0.92 changed that
has broken things.  There's also a changelog here:

http://forum.pfsense.org/index.php?topic=6729.15

Note two MFGPT-related entries in 0.92:
	
	- disable CS5536 diverse device power management to avoid
MFGPT /
	  interrupt issues.
	
	- MFGPT issues: please observe AMD CS5536 data book section
5.16.3,
	  incorrect initialization sequence can HANG the system.


I'm assuming the first is messing w/ DIVIL_GLD_MSR_PM...
