Just a quick status report.  A hacked version of a new ACPI import does
fix things and I can suspend/resume multiple times just fine.  The issue
is with wake GPE handling.  I don't think it is the power code at all.  In
fact, the BAR restoration allows my console video to work after resume
now whereas before only X worked.
