            Hi!

            Is there anyone writing a driver for a D-Link DWL-G520+ card
            (apparently prism54)?
            The already existing driver for DWL-520+ (prism) does not work
            with the new 54/108 Mbps card. Probably it cannot be modified
            to work at all, because the Ethernet device chips might have
            to be different in these two cards. AFAIK someone said the
            older card had a very slow Ethernet part which just barely made
            it in the 802.11b speeds.

            When checking what the card reports of itself to the pci bus
            "pciconf -lv" gave me originally this...

    none0@pci0:14:0: class=0x028000 card=0x3b041186 chip=0x9066104c rev=0x00 hdr=0x00
        vendor = 'Texas Instruments (TI)'
        class = network

            I made the following additions to /usr/share/misc/pci_vendors.
            (A couple of ATI Radeon 9200 entries were missing too.)

            Properly recognising the device id code naturally did not hint
            me to any direction where to start looking for a suitable basis
            or starting point for a new driver or modifying an old existing
            one. Linux people seem to have their own Prism54 team working
            on this hw. They even have a team web site "Linux Driver for
            the 802.11g Prism GT / Prism Duette / Prism Indigo Chipsets".
            How close is that to a good starting point?

            So, if someone is already working with this, it would be nice
            to know. If nobody else has put any effort in this yet, any
            hints helping me grab and modify pieces of existing code would
            be great.

            Cheers,
