More perhaps an answer?! 

Forum: Installing Linux using or onto a PCMCIA device

Reading the thread "Bug: Lockups on card insertion/removal..." I ask me, if the same recipe could help.

cat /proc/pci gives (lspci does not work on my laptop):
...

dump_pirq output:
Interrupt routing table found at address 0xfdf50:

  Interrupt router is device 00:07.0

Interrupt router at 00:07.0: Intel 82371AB PIIX4/PIIX4E PCI-to-ISA bridge
  PIRQ1 (link 0x60): irq 11
  PIRQ2 (link 0x61): unrouted
  PIRQ3 (link 0x62): unrouted
  PIRQ4 (link 0x63): irq 5
  Serial IRQ: [enabled] [continuous] [frame=21] [pulse=4]

So it seems me that irq=5 is at the place of irq=15 at the former thread. That's why I set
	PCIC_OPTS="poll_interval=100 pci_irq_list=5"
in /etc/rc.d/rc.pcmcia and now my card is recognized.
