Doing a little digging, it seems like

. /platform/pc32/i386/i686_mem.c

*might* have the necessary infrastructure to remap the MTRR's per the 
thread referenced,

but:

. /platform/pc32/acpica5/acpi_wakeup.c

doesn't seem to be using this infrastructure..

I'm no where near reaching an understanding of this yet,
but I'm wondering 3 things:
1) does anyone have ACPI (instead of APM)
   sleep / suspend / wakeup working on Dfly ?
2) If so, what machines are being used ?
3) Same question for other BSDs - my understanding is NetBSD is most
   'advanced' w/r/t power managment - but I'm not 100% on this ...
would looove to have a sleeping / resuming / scaling laptop running some 
BSD flavor.. am willing to work towards that end, esp. w/r/t Dfly -
trying to chart a course to figguring this out.

Thanks all,

- Chris
