Sorry, missed that one.

Well, it should be fairly easy to determine - later tonight I'll hack my
way through the source to coffboot to have it show me the values of those
parameters.  Unless I'm mistaken, the parameters should be in r3, r4, r5,
r6, r7; I'll print those values out, etc.

It seems to me that they aren't really needed passed - don't they come from
boot-file in the firmware?  We could grab them with getprop.

So if this is one of the problems, we should be able to fix it.

I see.  I'll let you know what effect changing it has on a PowerMac.

Just fills in the defaults since no .note is present, I assume?  No need
for us to worry about that, then.  Although...interesting that real-size
and virt-size are 00100000 in my PRAM and -1 there.  Once again, I assume
it's irrelevant.
