It's the real one, Qemu stores configuration variables in nvram, entry.S 
reads the memory size which is printed here.

Like this:
new-device
  " STP1012PGA" device-name
  " cpu" device-type
  " " encode-string " performance-monitor" property
  d# 256 encode-int " mmu-nctx" int-property
  d# 32 encode-int " cache-line-size" int-property
  d# 512 encode-int " cache-nlines" int-property
  1 encode-int " mid" int-property
finish-device

It's in the patch in arch/sparc32/init.fs.
