Narrowed this down some.  Posting for
future Googlers.

Looks like the culprit is probably

   What's new and what changed from 1.7.7 to 1.7.8
      * Drop support for Windows NT4 prior to Service Pack 4.

per

   http://cygwin.com/cygwin-ug-net/ov-new1.7.html

Looking at the NXWin log output I get
the feeling it's depending on some old
filename semantics.  First bit of strangeness
is that the output of NXWin should go
to 'winlog', but in the post 1.7.7
secnario its written to 'svclog', which
is intended for the parent of NXWin.

The place where NXWin breaks down is

   Dispatch: Exiting from the dispatcher with exception [2].

also this seems particularly not good

   Error: Cannot rename 'C:\Users\username\NX73F8~1/D-W2K8NXCLIENT-85AF85472A34ED995AD4DFCD5F3BEFBD' to 'C:\Users\username\NX73F8~1/T-D-W2K8NXCLIENT-85AF85472A34ED995AD4DFCD5F3BEFBD'. Error is 'Permission denied'

In case it's relevent, have 'fstab' setup like so

   none /cygdrive cygdrive binary,posix=0,user,noacl,auto 0 0

It's a guess, but I'd say that NXWin
might require work to eliminate some
obsolete file semantics.  On the other
hand the issues could all reside in the
X server code and simply recompiling
and relinking NXWin in the latest X11
tree will make it right.

Till then the 1.7.7 DLL does the job.
