It's hard to make money off of a $60 distribution if you don't have
enough volume, and there isn't enough volume for a mips desktop
distribution.  If you're talking about embedded linux support, Hard Hat
Linux from MontaVista runs on mips, sh, x86, ppc, xscale, and SA. But
we're talking about thousands of dollars for a product subscription.  If
you don't want to pay that type of money for support, I think H.J. Lu
has done a tremendous job in porting rh71, and you always have the
mailing lists.
