There we go. The usual SELECT dependency hell again...
Would changing SSB_PCMCIAHOST_POSSIBLE to tristate also fix it?
What would be the sideeffects?

I think this PCMCIA=y is not good, because it's perfectly
legal to build PCMCIA as module, while SSB and everything
that depends on SSB is also a module.
Would tristate fix that?
