Got initialization working correctly, and hopefully 100% of the time for this 3Com card. Infrastructure is working in 40 and 128 bit encryption, Ad-Hoc (IBSS) is working in 40 bit encryption (which is the only thing the firmware supports at this point), and I've added some more Wireless extensions to the driver. In short, I released version 0.2.2 of the poldhu_cs driver, and it's working like a charm for me.

I still have to finish the implementation of all the Wireless extensions and handle a card reset state, but that's for the next version. Which should only be a couple of days. ;)
