   That was my initial thought too, but 12390:430e06e2aa08 is the change
that set the PM1A_EVT_BLK_ADDRESS to it's current value, and it
indicates it's for ia64.  So my guess was that we both have this at the
same address.  I'm not sure why cset 12390 doesn't make use of the macro
with the acpi_map() call it makes though.
