Here are results of my testing booting OS X on latest trunk Logs in attachment
Not patched ones (fails without get-key-map): 10.0.log 10.2.log 10.4.log
Patched with gsoc get-key-map patch: 10.0-gkm.log 10.2-gkm-panic.log 10.4-gkm.log
Patched with gsoc divide by 0: 10.2-gkm-dvb0.log
Logs from patched boot without CIF: all-without-cif.log
10.2 ones show that there is need for some solution regarding division by 0, some notes from my talks with Mark:
My g5 machine returns 0 when dividing by 0, no warnings are printed: 0 > 0 0 / ok 1 > . ok 0 > 0
0 > 2 0 / ok 1 > . ok 0 > 0
Question is how to implement it, or maybe just use gsoc patch?
Also it seems that Mac OS X seems to provide it's own fill-rectangle and draw-rectangle it prints: FILL-RECTANGLE isn't unique. and also similar message when I apply gsoc draw-rectangle patch so it seems that this one isn't needed
Another problem is that it seems to be unable to open/load kernel.
On graphic side of things it seems to draw things better than with gsoc patches, graphics are not weirdly resized, but there is not much to see except boot folder graphic (10.0)/white apple(10.2, 10.4).
