[Lcdproc] Can't get this thing working...

now i get the display working. Not directly connected to the parallel
port, but a bit more complicated:
I used an i2c-tiny-usb to get a i2c-* device. Then i used a little
piggy back pcb with the i2c-connection as described in the docs and
put it at my existing panel-pcb (fortunately all signals are fed
through 10R resistors and can therefore be cut :-) ). I changed the
LCDd.conf hd44780-section to:
et voila, the display starts with
LPT 0x21 bl
and after a few seconds the server screen starts with the puming heart in
the upper right corner. So the i2c-driver seems to work perfect even it
is a bit slow (that's the drawback when using a "10-parts-single-chip"
USB2I2C-bridge that gives a throghput of only 50kBits/s). But it's ok
One open question:
Can i use the keymatrix connected to the LPT in parallel?
How do i have to extend my LCDd.conf (somewhere i read, that i can use
more than one devices in the hd44780-section...)?
