I went to CompUSA [1] and picked up a few Intelogis PassPort [2] units. The package included two PC units and a printer unit and the price wasn't all that bad. I was able to install the Linux drivers [3] for the PassPort on the laptop easily enough, as the Linux kernel was compiled to support modules (because of the PCMCIA support).
Try to install the modules on the primary system here. Oops, I don't have module support in the kernel.

Try to install the modules on the primary system here. Oops, seems I included the parallel port driver in the kernel and that's grabbing the port. Need to remove that driver.
