MacOS definitely sees it.

So does NetBSD, sort of -- Here's the memory line from /usr/bin/top:

Memory: 10M Act, 4016K Wired, 70M Free, 192M Swp free

and some vmstat output:

 procs   memory     page                       disks         faults       cpu
 r b w   avm   fre  flt  re  pi   po   fr   sr f0 s0 s1 m0   in   sy  cs  us sy id

NetBSD does appear to use all 96MB; it just reports it wrong at boot time.
