uConsole R-01 - Compile Kernel Modules? HowTo request

I would love to be able to compile a module or set of modules from the cpi kernel source tree.

Problem statement:

Desire to compile missing pl2303 kernel module or have instructions on how to compile a kernel module.

lsusb -tv
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=sunxi-ohci/1p, 12M
    ID 1d6b:0001 Linux Foundation 1.1 root hub
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=sunxi-ehci/1p, 480M
    ID 1d6b:0002 Linux Foundation 2.0 root hub

            ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P

Key element missing is that Dev 8 with the Driver= missing

All that said, very happy to help to try and contribute if someone has a reference for me to follow.
