IBM R40: to pcmcia or not to pcmcia

I keep having problems with my IBM R40: the pcmcia interface just will not work. Very iritatingly I keep getting:

kernel: Yenta: CardBus bridge found at 0000:02:00.0 [1014:0528]

kernel: Yenta: Using INTVAL to route CSC interrupts to PCI

kernel: Yenta: Routing CardBus interrupts to PCI

kernel: Yenta TI: socket 0000:02:00.0, mfunc 0x01d11002, devctl 0x64

kernel: Yenta TI: socket 0000:02:00.0 probing PCI interrupt failed, trying to fix

kernel: Yenta TI: socket 0000:02:00.0 no PCI interrupts. Fish. Please report.

kernel: Yenta: ISA IRQ mask 0x0000, PCI irq 0

kernel: Socket status: ffffffff

On a kernel that should be able to handle it (2.6.7-mm3) Even without acpi, apic and other magic. The only good fact is that also when using XP it sometimes behaves strangely...
