Yesterday new project was born: writing free driver for Marvell 8385 based WLAN cards. Currently there are few persons involved including me and Holger Schurig. Join us if you are interested.
Holger did research and found that driver for 8388 (USB version of chipset) is GPL licensed and contain newer version of WLAN interface then cf8385 driver which we got from company which sent us cards. I diffed both versions and it looks like USB version has some support for 2.6 kernel added already.
We currently does not have any timeline for release — first we need to get it built against 2.6.19-rc kernel.
