Hi Mark,

Address not Aligned
^^^^ After the unaligned access OBP is not properly initialized.
See the bug 1262081, reported by Peter Bartoli.

Ah... I wonder if OBP doesn't like something in the QEMU,tcx.bin FCode
initialisation function? If you temporarily rename the file (which can
be found in the share directory) to something else, does boot start to
work again?
Thinking about it, I suspect I'll need to add some code to the OpenBIOS
FCode ROMs so that they only initialise if OpenBIOS is detected. This is
because there is code there that tries to get information from QEMU
about the screen width/height/depth etc. which will obviously fail on OBP.
ATB,
Mark.
