Err.. Drop into the firmware, and take a look, dood:
ok dev /memory
ok .properties
reg 0e000000 00800000
0c000000 00800000
0a000000 00800000
08000000 00800000
available 0e774000 00060000
0e6fe000 00001000
0e600000 000fd000
08001000 000df000
As I recall, the `reg' property indicates where each RAM slot is mapped into
physical address space, whereas `available' indicates which memory regions
are available for use by client software (i.e. the NetBSD kernel). Note
that if a particular slot isn't filled, then it does not appear in the
`available' property.
