Let me share my dirty little fix for this (and let Guy debunk it); it does
not even require patching a binary.

# mv /etc/getty /etc/getty.x
# cat > /etc/getty
ulimit 4096 # OR WHATEVER
exec /etc/getty.x $*
^D
# chmod 544 /etc/getty

# exit

motd etc.

$ ulimit
4096
$

Note: if you have uugetty on some ports you will need to do a similar thing
for it.
