If you are running ISC 2.2, you can do

stty ENH_C80x43; echo "[=0;7C\c"; LINES=43

on a VGA and it works.  The echo is to fix console driver BD that loses
the cursor when you change to 43-line mode.  You can also use setcolor -c.

WARNING: doing this on ISC systems prior to 2.2 is likely to cause your
console go south and require a reboot.  I don't know what happens on non-ISC
systems.
