  The pcmcia code choose irq based on a probe, not in the kernel configuration.
  This is this way because some laptops hard-wire intr lines, and they're not
available although they seem to be.
  If you modify pcic_isa_intr_list[] in /sys/dev/isa/i82365_isasubr.c to
try irq 15 first, does it help?
  Using a GENERIC kernel does shows the same problem?
  This doesn't look to me like a irq problem, tho.
