to solve that problem change following entry in setup-bus.c in the kernel sources:

old entry:
#define CARDBUS_MEM_SIZE (32*1024*1024)
new entry:
#define CARDBUS_MEM_SIZE (48*1024*1024)

and recompile the kernel.

PCI allocation failed

PCI: Failed to allocate mem resource #0:1000000@38000000 for 0000:03:00.2

to solve that problem change following entry in setup-bus.c in the kernel sources:

new entry: 

#define CARDBUS_MEM_SIZE        (48*1024*1024)

and recompile the kernel.
