A few things that I came across when wanting to run a Mac OS partition under windows.
Mac support need to be complied into the kernel. You need a valid, legal Mac ROM image to run the OS.
Below is the link for the guys who have really put in the hard yards.
Don't know what their current level of development is, as it's been about a year since I wanted to run the Mac OS under Linux. Although Mac's multomedia apps ... hmmm, now you've got me thinking.
Anyway, good luck.
