No, I don't beleive it can. The shell must keep track of symlinks
it follows, AIUI, which bash does, and zsh does too going by your
description. (After you `cd /home', your current working directory *is*
/usr/home (with the symlinks as above), as returned by getcwd(), but the
shell keeps track of where you think you are, so `cd ..', etc, works
appropriately. At least, I think it does, I haven't checked the code,
but it must to something along those lines.)

I find bash much nicer for interactive use than sh. (Well, a bit nicer,
anyway.) Bash can do what you want with PS1='\w\$ ' or similar, though
similar solutions exist for sh: try searching this list's archives from
www.freebsd.org.

In your shell initialization file,
case `id -u` in
0) PS1="`pwd`# ";;
*) PS1="`pwd1$ ";;
esac
should do what you want, in a sh-type shell. csh probably has similar
constructs, check the manpage. In my bash PS1, I have '\$', which expands
automatically to "#" if uid == 0, else it expands to "$".
