i tried a 2x16 which had been working with a small pic micrcontroller and a 
new 4x20 also a hd44780

heres lcd4linux.conf

Display HD44780
Port 0x378
Size 20x4
Bits 8
Wire.RW "GND"               #RW (pin 5 lcd hardwired to ground)
Wire.RS "AUTOFD"           #RS  (pin 4 lcd to pin 14 DB-25 "Autofd")
Wire.ENABLE "STROBE"     #E (pin 6 lcd to pin 1 DB-25 "strobe")
Wire.GPO "INIT
Row1 "** %o %v **"
Row2 "%p CPU %r MB RAM "
Row3 "BUSY %cb%% $r 10cs+cb"
Row4 "LOAD%1L%L$r10L1    "


the data lines (DB0........DB7 on the display,DB1 ....DB8 on the parrallel 
port)are connected directly
RS pin 4 lcd to pin 14 "autofd"
RW hardwired to gnd
E pin 6 lcd to pin 1 DB-25

hope this can shed some light
thanks
