I'd strongly prefer the option to build QEMU's own binaries and
distribute them in pc-bios/. Downloading this 190M tarball is a nuisance
and depending on their continued existence on the Oracle server is a risk.

Where does the dependency on Solaris 9 come from? You should be able to
run unmodified Solaris 9 binaries on eg. Solaris 10...

Best,
