Comment (by wmb at firmworks.com):

 Here is a trace showing correct operation with the test version that will
 become the next release.  The memory sizing and reporting code has not
 changed for several releases. OFW-5 is the same as the current version in
 that respect.
 So I am not sure what is going wrong.  The OS here is build 130 with one
 of the
 kernels from Andres' auto-build tree.  The kernel signature is shown
 below.
