i'm happy to copy the directories into our xorg-server tree and
have them ignored instead of deleted.  i could commit my work
in progress for Xalpha (which has used tsutsui's work above so
far, but i hit a cfb problem i didn't see an easy solution to
and moved on ...)

a README would be useful, of course.
