For qemu yes. Works fine on ppc (and if ds->bgr is manually set to 1,
shows the blue-footed penguin on ppc). [If the ds->bgr initialization
is omitted it hangs with a black screen and the spinning color wheel.
That's strange since bgr == 0 would be okay and any other value
should lead to a blue-footed penguin only.]

OK, I'll apply the patch.

For Q's interface I derived a patch against host-cocoa/cocoaQemu.m.
That works fine on OS X i386 and ppc hosts.

I have no idea...

But are you sure that we do not need 8-bit bgr? Q's patch inverted
that, too. How would I test that?

I think there in 8-bit mode the colours come from the palette indexed
by the pixel value, not directly from the pixel value.
