Comment(by cjb):

 Replying to [comment:12 wmb at firmworks.com]:
 > a) Using the SMI handling code that will be in A15, we could put an SMI
 trap on writes to the ACPI "go to sleep" register, thus letting OFW get
 involved in the final steps of suspend.

 I think my intuition is that this is worth investing in -- it's not the
 first time we've wanted to compare state before/after resume, and it
 probably won't be the last, even if this particularly bug turns not to be
 memory-related.  Make sense?
