With the appended patch on top of Tony's four, I get:

 mmc1: new SDIO card at address 0001
 firmware: requesting sd8686_helper.bin
 ...
 libertas: can't load helper firmware
 libertas: failed to load helper firmware
 libertas_sdio: probe of mmc1:0001:1 failed with error -2

So, progress.  What's the best place to get that stuff?
Do we know that this driver behaves with SDIO yet?
