Anybody want to give me a hint?  I'd start by copying lpbb, replacing the parallel port code with appropirate gpio calls.

I couldn't get iic to work, so I rolled my own userland bitbanging utility, based roughly on the OpenWrt code (minus some small bugs) and the datasheet.

I can read and write registers, but to my consternation, most of the functionality (MIB counters, ST controls, etc.) seems to be somehow disabled or just plain missing.

I'll try to get a basic utility up and running to use the basic VLAN mode (not the table-based mode) tomorrow.  Once that's working suffiently well, I could make it into a stand-alone driver, or see if it can be integrated into Aleksandrs work.
