Okay, I find a kernel tree there which, in 
debian/patches/0019-marvell_8686_8688.patch contains another 
libertas driver.

Unfortunately, the (Intel created) moblin.org webpage only 
supports the "http://"; access protocol to the git tree, which is 
rather inefficent. I'm currently trying to get this tree 
with "git clone --reference /usr/src/linux-git 
http://www.moblin.org/repos/projects/kernel-mid-2.6.24.git/";, 
and takes ages. Maybe they also made this tree from scratch, so 
that the reference to Linus' git tree won't help the 
downloading.



Okay, to the driver:

* it's GPL, so we can copy from it
* it's an if_sdio.c only-driver (and also contains something
   with bluetooth stuff)
* it's weird, as this patch contains two wlan_11.c files
  which differ. This is true for effectively every wlan_XXX.c
  file.
* it looks similar to what Marvell donated originally to OLPC
* compared to the current in-kernel libertas driver, it has
  some more code for 802.11a frequencies
* older Marvell drivers contained firmware as *.h files, this
  driver now uses #include <linux/firmware.h> as well

As this driver is sdio-only, and we have already other libertas 
drivers supported in the kernel, it would never accepted as-is 
in mainland kernel. Therefore I invite Marvell and Intel to 
participate with the in-kernel libertas driver. I understand 
that for Intel this might not be possible immediately, because 
the current libertas driver might not work on their 
Atom-reference platform, but I guess in the long-run could be 
beneficial.

I CC'ed feng tang from "git log 
debian/patches/0019-marvell_8686_8688.patch" therefore :-)
