Hmmm, sounds strange as I've never had any serious problems in installing
NetBSD on a AXPpci33 of similar configuration - just faster... ;)

My suggestion would be to check the SRM console version and, if needed,
upgrading to the latest version available from the 
(5.4 by memory which also contains a console for AXPpci (noname)

BTW: I am using second hand 15ns cache chips from old Intel
motherboards which shouldn't cost you anything... Just look around at
a computer recycler... ;)

hope this helps
