OK guys. I decided to just write a simple guide to how I modded my Packard Bell IR receiver to actually plug directly into a serial header, so the IR port can be built inside your case...
You can get a PB IR remote & receiver very cheaply HERE Sun is very reliable...
This was spurred by my various attempts to get the built in IrDA port to work with an IR remote... Unfortunately the architecture is just too different so I had to drop that idea.

I still wanted the IR port inside the book pc.. so I opened it up & removed the IrDA port. Replaced it w/ the PB IR receiver.

The Packard Bell receiver has 5 coloured wires, plus bare lead ground.
Below is a schematic of the serial connector (female) (ie. the connector on the PB remote)

Below is a schematic of the serial connector (male) (ie. the connector on the serial header)

as you can see - the pin holes are #'d backwards on the female connector - so pin 1 goes into hole 1.
This was very beneficial as my serial header had 9 wires & the red wire #1 corresponded to hole #1. (as did #2, etc.) Therefore, you don't even really need the schematics anymore.. Count from the red wire #'s 1-9... They correspond to the serial pin holes.

The PB receiver wires correspond to the following pins.
pin 1 = Blue wire
pin 2 = nothing
pin 3 = Orange
pin 4 = Green
pin 5 = White
pin 6+7 = Brown
pin 8+9 = nothing

I tore the 9 wires from the serial header into 5 single wires & 2 sets of 2 wires (6&7 + 8&9)
I immediately put heatshrink over wires #2, and 8&9 together.
Wires 6&7 I stripped & twisted together to solder to the brown wire from the PB remote..
All the others were soldered to their PB receiver wire counterpart.
The bare lead for ground was covered completely in heatshrink.
All of these were then covered w/ a larger heatshrink tube...

Pics soon, my Dad has the digicam.
