I went on with investigating that problem and found the problem,
though I'm not sure if that solution is acceptable..

seems like the memory range gets preallocated in setup-bus.c, and
CARDBUS_MEM_SIZE defines that size.

I changed
#define CARDBUS_MEM_SIZE        (32*1024*1024)
to
#define CARDBUS_MEM_SIZE        (48*1024*1024)

and now the system is able to allocate the resources for the 3rd
pci/pcmcia function.

Can anyone please have a closer look at it too? I think the whole
implementation isn't really good there..

so this is the new output of iomem:
$ cat /proc/iomem
...
30000000-35ffffff : PCI Bus #02
  30000000-32ffffff : PCI CardBus #03
36000000-360003ff : 0000:00:1f.1
39000000-3bffffff : PCI CardBus #03
  39000000-39ffffff : 0000:03:00.0
  3a000000-3affffff : 0000:03:00.1
  3b000000-3bffffff : 0000:03:00.2 <- this one failed to allocate previously
3c000000-3effffff : PCI CardBus #07
41000000-43ffffff : PCI CardBus #07
...
