Nice - Have you looked at using the mwait deeper C-States rather than halt? 
I think the "msr" portion looks like it will handle the entire Micro Core architecture 
- that would be really nice - Judging from the papers published by intel and from the
general discussions on the net - it seems like

a) P-States are the prefered way of reducing power
b) EIST - adds additional savings
c) ODCM - should only be used for Thermal emergencies as it does not redure the power 
d) TM2 or TM1 must be enabled but TM2 is prefered 

Would it be possible to seperate the "ACPI" part from the other "Mac patches" as I think
its of more general use?
