Ok, so I see the same thing with a Ricoh PC104+ to Cardbus adaptor on a little industrial PC, except I'm using an Atheros-based wireless card instead. I get this with 2.4.25:
01:00.0 Class 0200: 168c:0013 (rev 01) Subsystem: 1186:3202 Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Step ping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort - <MAbort- >SERR- <PERR- Interrupt: pin A routed to IRQ 12 Region 0: [virtual] Memory at d5120000 (32-bit, non-prefetchable) [size= 8K] Capabilities: [44] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot -,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=2 PME-

Again, any assistance greatly appreciated, and I'll test any proposed patches.
