Thanks, Artyom.
Heads up: Solaris 2.5.1 doesn't boot with OpenBIOS. I'll be happy to
help with some regression testing, if you like.

Title:
qemu-system-sparc in qemu 1.7.0 fails to boot with Sun ROM
Status in QEMU:
New
Bug description:
1.7.0 seems to have broken booting on SPARC ... at least with a Sun ROM.
Everything fails with "data access exception." 1.6.{1,2} qemu-system-sparc
binaries both boot the same images that 1.7.0 fails to boot.
