Does your config.opts file work better than:

  include port 0x1000-0xffff
  include memory 0x08000000-0x0fffffff

You do not need to manually exclude regions that are marked in-use in
/proc/iomem and /proc/ioports because the PCMCIA modules will never
allocate a region that is already allocated.  You can just specify the
full range of PCI bus addresses and let cardmgr go at it.
