 It's futile to try to support linux/m68k/ELF binaries under a.out. You
 can't even run NetBSD/m68k/ELF binaries under a.out.

 For what it's worth, I'm able to build a GENERIC kernel plus "options
 COMPAT_LINUX"  with the 1.5AZ/mac68k/ELF toolchain. I don't have any
 m68k/linux binaries to try it with, though. The switch to ELF on
 mac68k isn't even official yet, but I'd be happy to send you the
 kernel, if you'd like to test it, or you should be able to build one
 yourself fairly easily using the new toolchain mechanism in the
 current sources.

State-Changed-Why:  

John has confirmed COMPAT_LINUX to be working on mac68k now. However, amiga 
is still broken (even after the ELF switch). 

One hunch is that it may be due to Amiga's 8KB MMU page size...
