Yes, it's a neat trick *if* the only thing people changed was the install
drive.  If they change the path, all bets are off.  I'm surprised you
don't actually customize startxwin.bat (and similar files, like
startxdmcp.bat) in a postinstall script (which can run under a Cygwin
shell, and thus know the root of the install).  You could choose a
template value, e.g. "%$CYGWIN_ROOT$%", and replace that with "`cygpath -w
/`" using, say, sed.  If you're interested, I could whip up an example
postinstall script for you in the next week or so.
