There is also no numeric value in the relevant line of my kernel config.

I would think that if you can't use ptys they don't exist -- but you might 
still have references to non-existing ptys in /dev/

Are they listed in /etc/ttys? -- apparently this is needed for some 
applications to know they exist.

My check for real existance of ptyq0/ttyq0 was to enter
# cat /dev/ttyq0
in one console window and
# echo fred > /dev/ptyq0
in another.
'fred' then appears in the first window and both commands complete.

I would have thought this was pretty strong evidence that at least this 
master/slave pair actually existed.

(I understand that xterm will not find all 256 ptys -- apparently some 
limitation in xterm -- but should be able to find at least 64.)
