In 0.9 they setup the ed0 driver to used shared memory at a different
location then the ec0 driver was setup for (it used to be at 0xd8000 and
is now at 0xd0000).  This wouldn't be a problem, but the 3c503 doesn't
support having shared memory at 0xd0000, so you need to recompile the
kernel.

Maybe they should post another kernel copy disk that has ec0 support or
has ed0 at 0x0d8000.  If there is a high demand and the netbsd folks
don't want to do it I could put a kernel on my ftp site
(phred.pc.cc.cmu.edu).
