We're going to need some libertas debug output I think.  Also, what SDIO
controller do you have?  "lspci" should tell us since I think your
controller is a PCI-based device.

You can get libertas debug info by using this option when loading the
'libertas' module:

libertas_debug=0x5063a7

That can also go into /etc/modprobe.conf or /etc/modprobe.d/local.conf
as:

options libertas libertas_debug=0x5063a7

and you'll get a lot more spew in dmesg about what's going on.
