Thanks, applied all.
Whilst updating to OpenBIOS SVN and qemu git head to test these patches,
I've found a regression with qemu-system-sparc64 and
debian-504-sparc-netinst.iso. Rather than getting to the end of the
kernel boot and being unable to mount the root filesystem, instead I now
get the following fatal trap message:

Aborted
Digging deeper, it seems that this was something that was introduced
earlier than the last set of patches. Reverting to OpenBIOS SVN r777 and
using 'git bisect', I can identify the offending commit in qemu git as
2aae2b8e0abd58e76d616bcbe93c6966d06d0188 "sparc64: fix pstate privilege
bits". Does that help at all?
ATB,
Mark.
