I assume that the driver interface at least would need to be open-sourced before it could be modified for pdaXrom.
Hiroshi at C-Guys emailed recently that they are going to look into the stability and conflicts I experienced with the Cacko ROM. Apparently, it was tested on the Sharp ROM. I pointed out to C-Guys that people who specifically needed WiFi on their SDCard rather than the common CF cards are probably pushing the Zaurus to be a mini-laptop more than a PDA, and so are likely to be running something more powerful than the Sharp ROM.
Is anyone using this card and driver on the Sharp ROM?
