that is only for the early C7, as I've been told by Centaur.  C7-M should
definitely support the ACPI states.  So better to disable both.

did you actually check if the power transitions are on longer happening?

there is JTAG on the CPU, but only for EXTEST/INTEST, i.e. access to the actual
signal lanes for making sure all the BGA pads are soldered and actually connect
to the right signals of the next component on the board.  There is no embedded
ICE or anything of that sort.  Also, your board most likely doesn't have JTAG
on an accessible connector, since it's out of mass production.
