Is this for a BIOS that is reporting non-contiguous Cx states or is this a 
patch to let your custom Intel Cx driver work?  If the latter, I would rather 
have the driver export a contiguous range of virtual Cx states (what ACPI 
actually does under the covers) rather than change our code to allow sparse 
ACPI Cx states.
