I have ran in to that problem on a solaris machine before.
And I am guessing that it can be done on an HP also.?!
What you do is boot to a cdrom (like you are going to install it)
and then openwindows will come up (in root), then you just
open up a cmdtool like any other time, mount /etc to /mnt or /a
and then edit the passwd file, reboot and you are back to normal.
