I have been unclear on the state of X on ultrasparcs.  Could someone
knowledgeable please comment on up-to-date status of the following
situations (e.g., whether to use USE_XF86_4, and whether a reachover
build or a xsrc build is preferred).

1.6.2/ultra2 (sbus machines, really)
1.6.2/ultra5 (pci bus machines)
current/ultra2 (sbus machines, really)
current/ultra5 (pci bus machines)

It looks like src/x11 builds are unpreferred, but presumably if there
is broken assembler then it should be easy enough to change a makefile
to not use it.
