Thanks for the quick reply.  Patch looks OK on my system... it boots
(which is very good :) and I see

    system 00:01: [io  0x0400-0x047f] has been reserved

however I don't see the "ACPI CPU throttle" region reserved in
/proc/ioports... haven't debugged why acpi_processor_get_throttling()
isn't getting called or what is happening yet.

Will dig a bit deeper and let you know.
