Yeah, maybe it's just the yaboot versions (1.3.16 for Jessie, 1.3.17
for Sid), that makes the difference.
It's annoying that something has regressed here though: is there an
official git repo for yaboot to check out the differences between
1.3.16 and 1.3.17?
The fact that it still works on real hardware suggests that something
has changed here: is it possible to generate a test ISO using 1.3.16
yaboot to see if that starts working under QEMU again? That would
narrow things down immensely.
With QEMU would it be possible to follow the approach of John Ogness
([1])? He used yaboot v1.3.16 from a USB stick and then loaded the
config file from the Debian Sid netinst disc.

That's an interesting hack. I've actually just managed to find the
offical git repo at http://git.ozlabs.org/?p=yaboot.git.
Is it possible to change the ports build to produce a -O0 -g yaboot
binary or point me towards how to alter the existing ISO with something
I've built myself via a cross compiler?
With that I'm happy to step through the yaboot binary against the source
via QEMU's gdbstub to figure out what is going wrong.
(BTW this is assuming that there are no local debian patches applied?)
ATB,
Mark.
