Thanks for digging this up. I wasn't aware of this particular issue before
and I agree, this needs to be addressed. I hope that I didn't cause too
many DOS partitions to be misdetected. Sorry for the inconvenience if I
did. The Atari partition table code has been working great for Debian/m68k so
far though.

I don't know by heart, but chapter 9 in this Atari filesystem reference
might help us:

I have also CC'ed the Linux/m68k and Debian/m68k mailing lists in case some of the
guys there knows the answer faster.
Again, sorry for the inconvenience this may have caused. I will look into
how we can improve atari_probe().
