Certainly if there were some funding available, this is something that I could look
at if required. Currently my free time is limited (and already fairly busy) but with
sponsorship there is the potential to allocate time within the working week.

I must say I'm surprised that HFS+ doesn't boot - certainly I see images in QEMU that
require both, and OpenBIOS has booted them successfully for many years.
