actually - maybe i should have mentioned this - it can't have anything to
do with unix98 ptys, as i didn't bother with them either. i don't have
the support compiled into the kernel. i always think of the devices in
question as ttypX, because i never go over the `p' series, but it's
actually just the standard /dev/ttyXX devices, *not* pty.

i guess i will try upgrading the libraries again and see if that helps.
xterm is indeed suid root as it should be.

i did initially compile with pty support just to try it out, but when i
realised it meant recompiling and/or finding different versions of
everything, i jumped ship. :)
