Ricoh is PCI Right?
Try putting "irq_mode=0" it is somthing like PICS_OPTS in your pcmcia stratup script, Check Bios Also (IRQ) and leave all to auto or remove ISA IRQ...
Check manual foe i82..Pcmcia Module there is explanation how to make this PCI-PCMCIA Bridge work. I am 100% Shure it is pcmcia-bridge problem no hostap or linix-wlan driver problem
