2.6.17-rc[56]-mm*: pcmcia "I/O resource not free"

[Andy Isaacson <adi@hexapodia.org>]

The PCMCIA slot on my Thinkpad X40 stopped working sometime between
2.6.17-rc4-mm3 and 2.6.17-rc5-mm3, and is still not working as of
2.6.17-rc6-mm2.  There's one diff early in dmesg that looks interesting:

 ACPI: PCI Interrupt 0000:00:1f.6[B] -> GSI 17 (level, low) -> IRQ 177
 PCI: Setting latency timer of device 0000:00:1f.6 to 64

 pcmcia: parent PCI bridge Memory window: 0xd0200000 - 0xdfffffff
 pcmcia: parent PCI bridge Memory window: 0xf0000000 - 0xf7ffffff

Then when I insert the card, instead of

 pccard: PCMCIA card inserted into slot 0

The card I'm trying to use is a "PQI Compact Flash Adapter", which
appears to just be some wires connecting the PCMCIA pins to the CF pins.
The CF card is a "TwinMOS Ultra-X 140X 1GB" card, part number
FCF1GBUPS-K W543F5TM0832.
