Sorry for diverting the discussion to this unrelated topic.  This is not
an alignment, this is a mismatch in the size of ioaddr_t on ARM between
the kernel and pcmcia-cs plus insufficient protection against fools like
me who use relative path to the kernel when configuring pcmcia-cs.

The fix has been sent to David Hinds and will appear in pcmcia-cs-3.1.34, 
but you most likely don't need it:
