Its a long time since I regularly had to worry about SPARC boxes (not) 
booting so may be the difference between virtual & physical addresses 
but I notice that some of the addresses in the register dump have 
non-zero values in the upper 32 bits but the memblock values have zero 
in the upper half.


memblock reserved: ADD [0x0000007fcc0a40-0x0000007fcc0a4e] node 1
memblock reserved: add [0x0000007fcc0a40-000000007fcc0a4e] node 1 @767

But a similar address in the registers has fffff800 in there.

o4: fffff8007fcc0a4d

I know that there are a number of explanations why things would be 
different (32 bit acesses etc) but it could explain things plus we would 
be talking 64 bit addresses in the kernel.

Just a thought.
