How to increase the max pty's on Freebsd 7.0?

[Steven Hartland]

I knew his sounded very familiar, seems I asked the same
question back in 2007 for 5.4 just it was capped at 256:
http://lists.freebsd.org/mailman/htdig/freebsd-hackers/2007-October/021852.html

I'm sure I also remember saying this limit had been removed in 7.x
but looking in the source for pqrsPQRS it seems there are several
places where this still hard coded:-

contrib/telnet/telnetd/sys_term.c:      for (cp = "pqrsPQRS"; *cp; cp++) {
lib/libc/stdlib/grantpt.c:#define       PTY_DEV1        "pqrsPQRSlmnoLMNO"
lib/libutil/pty.c:      for (cp1 = "pqrsPQRSlmnoLMNO"; *cp1; cp1++) {
sys/kern/tty_pty.c:static const char names[] = "pqrsPQRSlmnoLMNOtuvwTUVWxyzXYZ";
sys/kern/tty_pty.c: * pts == /dev/tty[pqrsPQRSlmnoLMNO][0123456789abcdefghijklmnopqrstuv]
sys/kern/tty_pty.c: * ptc == /dev/pty[pqrsPQRSlmnoLMNO][0123456789abcdefghijklmnopqrstuv]
usr.sbin/ac/ac.c:                                   strchr("pqrsPQRS", usr.ut_line[3]) != 0 ||

So the questions are:-
1. Is the fix to this still to just to update these settings?
2. Is there any significance to the upper case lower case thing?
3. Are there any other restrictions on the letters that can be used?
