Have you set up the Chip Select stuff correctly for your board (see
gpio_cs in the platform data)?  That seems to be board-dependent and
there's not a good generic way of doing this in the current kernel
sources.

That error is the first error that will get reported when the driver
actually tries to talk to the card, which requires that the Chip Select
stuff be set up correctly.  If you think you've got that already set up,
can you manually inspect whether or not the libertas device has actually
been selected on the board?
