Most likely the reason that the 68020 adapter doesn't work in the Unix PC is that the 68020's Bus Error/Address Error stack fram format is quite different from that of the 68010. The first time you get a page fault things will fall apart. Also, the power on diagnostics may check for correct bus error handling. Armed with the kernel .o files and a disassembler, you may be able to hack a working kernel.

Of course, the boot ROMS and the boot loader on the drive may need to be hacked for the 68020 also.
