Joseph, 
	I have tried this on my machine at home and it threw a kernel panic on boot. 
I cut the section of the dmesg out, if this helps..  If there is anything I 
can do to help you debug, please let me know.  As a point of note, I have 
removed the hwpmc from the config file and recompiled and the new kernel seems 
to work ok..
