Upstream kernel libertas driver has support for WEXT and works with
wireless extensions just fine.  The driver has been in kernels since
2.6.22, and the SDIO bits will be in 2.6.24.  I'd suggest using that
driver instead of the marvell reference driver, unless you have specific
needs for things that the upstream kernel driver doesn't support (yet).
If you do, please let me know and we can try to add it to the upstream
kernel driver.

The Marvell reference driver is broken for many WEXT things and doesn't
support WPA with WEXT, which is just wrong.

FWIW, I have a Marvell 8686 SDIO board and worked quite closely with
Pierre Ossmann to develop the SDIO support for the upstream kernel
libertas driver, so I'm pretty familiar with most aspects of it.
