Not that I know of, but it's probably only a matter of someone smarter
than me looking? I think what I want is a command line option that is
disabled when the server is setuid (or, frankly, run as root at
all?). This is purely a hack to show the xlease program working and test
KMS and X leases without needing Mesa changes.

I'll rewrite this as a command line option, which presumably involves
adding an option to the general xfree86 set.
