I experienced the same problem on a 5000/125 with a pmag-b.  It seemed that
the mfb console driver was broken, up until a few weeks ago, when patches
were submitted and (I believe) integrated into -current.  

If you have another pmax running netbsd, you could roll a nfsinstall kernel
from -current and boot it over the network.  

Personally, I had been running the thing headless from a vt100 until the mfb
stuff was tinkered with.  If you have an old vt terminal or a 386 with
kermit, you could just boot the thing headless, roll a -current kernel, then
switch to the console.
