I must have missed that message. I guess you mean this one:

It also works on OpenBSD/Sparc64 host, which is big endian. Linux/i386
works too, so 32 bit case is covered.

I doubt that this can be a problem in OpenBIOS, I find QEMU more
likely suspect. Can you boot any other big endian targets on PPC, for
example PPC?
