Well, unless your version of the shell allows a builtin function to be 
superceded, or you have the source (example: BaSH) then you have to resort
to ugliness.

WARNING: Ugliness is to follow.  If you are easily offended by ugly
         kludges to routine problems, do not proceed further.


Take your favorite binary editor (or use adb if you're hard-up), and walk
through the binary for /bin/sh; replace 'cd' with 'xx'.  Then your function
will work ...

	cd() {
		xx $*
		PS1="`pwd`> "
		}

Yep.  I told you it was ugly.

Cheers,
