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?
