The Overo FireSTORM uses the WI2Wi W2CBW003 - 802.11 b/g +Bluetooth part. using the Marvell 88W8686 SDIO/GSPI chip. The chip vendor recommends you use their WIFI driver and not the libertas_sdio driver supplied with the unit. I would start with sales @ WI2WI:

For our application, we wish to decode 802.11 packets on a consumer grade wifi module. I'm reaching out to anyone who has replaced the Gumstix Overo board in the E100-series machine with a wifi-enabled Gumstix board, namely the Overo FireSTORM. I have already replaced the board in our machine, but have been unable to get the wifi module to work (Everything else seems to work perfectly).
The FireSTORM has the exact same configuration as the packaged Gumstix board, but with the addition of a wifi module soldered on. I see no reason why reason it shouldn't work, and suspect it is a driver problem.
Namely, in my driver log, I found the following error:
lib80211: common routines for IEEE802.11 drivers
lib80211_crypt: registered algorithm 'NULL'
cfg80211: Calling CRDA to update world regulatory domain
libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman
libertas_sdio: failed to find firmware (-2)
libertas_sdio: probe of mmc1:0001:1 failed with error -2
Has anyone else attempted to do this? I've tried downloading the relevant linux-firmware files and placing them in /lib/firmware, but that didn't seem to work (same error).
