It's been a while... My recollection is that the /memory node ends up
specifying the physical memory that OBP occupies in the "reg" property, while
the memory available to Solaris' use is in the "available" property. I found
at least one instance where OBP takes 1000.0000 bytes at startup, but that's
on a per-platform basis and it's buried in the assembler code, so hard to
figure out at a glance.
