Are you aware of anyone running / fixing m68k Debian for vampire boards? They are getting fairly high performance (at least 4x of a 060/50 for cpu intensive work) and it seems to me that they are being well-enough engineered.

Ps. Thankyou for latest information about m68k and how to get a fully-working Debian chroot / nspwand ... it works great! :)

I know about the Vampire boards and I talked to one of the developers at the Amiga32
conference in Neuss, Germany.

The problem is that Vampire currently does not emulate an MMU that is compatible with
the Linux/m68k kernel. However, the FPGA they are using has its own MMU and the
Vampire developers speculated whether it could be used by the Linux kernel instead.

You're welcome. Please also have a look at http://m68k.info which brings news about new
development in the m68k community. You will find a talk about the upcoming M68k backend
for LLVM as well as a new qemu virtual machine type for m68k with 3.2 GB RAM and 128
virtual devices.
