If the space is mapped by the kernel, you can use /dev/allkmem
so, if the kernel maps the APCI tables, they should be visible there.
(If they're not mappable, then /dev/mem should not give access).

I think /dev/mem is unusable, /dev/mem maps the most of RAM/RWM
memory and not ROM/FLASH (or RAM/RWM copy of ROM/FLASH) memory
where APCI tables reside.
/dev/mem is driven by 'phys_install' memlist ( http://
cvs.opensolaris.org/source/xref/usr/src/uts/common/io/mem.c#633 ).
You can see actual memlist with mdb ( echo 'phys_install::walk
memlist | ::print "struct memlist" address size' | mdb -k ).
