There is still one unresolved issue that William's patches fixed. When booting Mac OS X using this command: "boot cd:,\\:tbxi", it causes Bootx to go back and try to find the partition that it can open. This search fails. A way around this is to just specify the partition to open: "boot cd:9,\\:tbxi". William made two patches that handles this situation:

http://lists.openbios.org/pipermail/openbios/2011-August/006640.html

I don't think these patches can be applied now, but I do suggest we come up with a way to only open the APPLE_HFS and APPLE_HFSX partitions. 

P.S. The recent patches to OpenBIOS have made my Mac OS 10.0 cd boot further than before. :)
