Changing the IO window of the cardbus bridge

[Richard Smith]

Kernel outputs the following:

Yenta: CardBus bridge found at 0000:02:05.0 [104d:816a]
Yenta: ISA IRQ mask 0x0c80, PCI irq 9
Socket status: 30000810
pcmcia: parent PCI bridge I/O window: 0x4000 - 0x4fff
cs: IO port probe 0x4000-0x4fff: clean.
pcmcia: parent PCI bridge Memory window: 0xd0200000 - 0xd02fffff
pcmcia: parent PCI bridge Memory window: 0x30000000 - 0x31ffffff

Probes to my CF ide device at 0x4050 don't work all I get are 0xff.

How can I change this IO window to another location to see if it works?
