I managed to find instructions on how to fix this problem on
It seems that these bridges have problems assigning IRQ's

I fixed the problem by specifying PCIC_OPTS="irq_mode=0" in me 
/etc/pcmcia.conf (for debian) using the i82365 PCIC driver.
I use pcmcia-cs and not the kernel pcmcia support.
Other hints are to put the PCMCIA bridge in the PCI Bus Master slot and 
force it to use a pci IRQ by adding pci_irq_list=<irq>,<irq> in 
PCIC_OPTS line. My understanding is there must be 2 irq's in the list.

I hope this helps.
