  I want to believe that this should be functional on the current
driver, or require some very basic patch to enable (but I only
have access to a sample mips computer with a smi 502...).

  Did you try with a checkout of the current freedesktop driver? It
would be good to know if there aren't any regressions. But from what
I could check, when comparing with sources in 1.4.9, all code checking
if is a primary card is already in the freedesktop driver, so, if it
doesn't work, it may also be a regression in the pci/vbe code in Xorg.

  Thanks. I looked at it, but I think everything it provides is
already available in the current freedesktop driver in functional
terms. But it is good to look at an older version to have a better
idea of how the code evolved :-)
