Funny, in the german forum at atari-home.de, there was a discussion
about using a 68010 in real STs recently, and they hit pretty much the
same problem as you:

If I get the messages right, the crash only happens when TOS tries to
load a NEWDESK.INF file on the boot drive - so if you rename that, it
should not crash anymore.
