Yes, but not the way you might think.  I have booted kernels to a
shell prompt on my Q700, but only with the SCSI disabled.  I have
been fooling with the SCSI driver and currently seem to be missing
an expected interrupt.  I'll be getting back to that when I finish
my current project.  You're welcome to help port when I get the SCSI
going.  In the meantime, you'd need access to a system running
NetBSD/m68k or to a system that's got a cross-development
environment set up.
