Nope, neither "nocst" nor "acpi=nocst" gave me back the C1 functionality...

Sorry about the red herring. I've patched 2.6.14 with the two acpi suggestions for this stable series that Greg KH posted (both single and combined):

[patch 10/26] ACPI: Prefer _CST over FADT for C-state capabilities
http://marc.theaimsgroup.com/?l=linux-kernel&m=113446277408937&w=2

[patch 12/26] ACPI: Add support for FADT P_LVL2_UP flag
http://marc.theaimsgroup.com/?l=linux-kernel&m=113446277427267&w=2

I thought nr 10 was the cause for the C-state regression, but neither effected my machine. C1 was used as it should. Now, I don't have the stomach for an un-cheerleaded "git bisect" of approximately four hours to find the real culprit. So unless someone waves the pompoms I'll slip quietly into the shadows, hoping the issue will disappear by itself before 2.6.15 is finalized.

Maybe it is this little patch that also has been applied in rc5?
http://bugzilla.kernel.org/show_bug.cgi?id=5452

If you have ACPI_DEBUG=y compiled in you should have seen:
"BIOS reporting wrong ACPI idfor the processor", then it might be this one.

Good luck,

Thomas

Thanx Thomas, but no, I tripped on a bug totally unrelated to Roman's. Found the culprit and reported + opened a bugzilla:
