This is for 1.6.3.  But it was enough to get me started.  After a whopping
5 minutes of testing, rc and hold mode work.  Here's a diff against
the 1.6.6 sources.  I can supply the makefile I used too, if anyone
wants it; the main thing is to define _POSIX_SOURCE and LINUX.

Now, to try restarting X with 9wm as the window manager...

Much thanks!
