But what about all those users that have some sort of "old" hardware
at home (like SparcStations 10, 20, 5, 4 and so on) ? It's nice to
support only the latest hardware, but here I think this way would be
wrong. We should support both the "old" hardware baesd on sun4, sun4m,
sun4d and the Ultra-based machines.
-------------------
I want to expand...

My input on developing only an UltraSPARC port is this:  first off, the
knowledge floating around about the Ultras is, in my experience, a lot less
quantitative than information you can find about most "plain-old-SPARC"
chips.  Take into account that there is a lot of work that has already been
done on sun4* architecture, in terms of other OS's, that is either GPL or
open source - providing this project with a broad base of knowledge to
borrow and build on.  Finish off with I don't have an Ultra that I can use
for development yet, so my contribution to a project that is only UltraSPARC
is going to be nil.

I don't think it is wrong to include Ultras in the port, but I believe it is
stupidity to disclude earlier SPARCs.

Disagreements welcome.
