Yes, just include "$?" in your $PS1 variable. I have something like:
export PS1='{$?}\u@\h:\w\$ '
in my ~/.bashrc to give me a prompt like
{0}tim@netbook:/etc$
where the "{0}" at the beginning shows the exit/error code from the
previously-run program.
I include the username ("\u"), short hostname ("\h"), and working
directory ("\w") mostly because I manage a number of machines, so it
helps me make sure I'm not issuing commands on some remote box I
admin.
