IRQ 0 for cardbus bridge on TP760XD - RH 8.0

I am trying to get my Level One WPC-0101 PCMCIA wireless network card to work on a IBM Thinkpad 760XD. I've tried with Debian unstable, but have now resorted to a standard install of Redhat 8.0, as that's the only system that seems to be supported by Realtek. The kernel is 2.4.18-14.

Problem: the cardbus bridge doesn't get an IRQ assigned. According to the output from the DOS utility that comes with Thinkpads, the IRQ for the first bus should be 3, and for the second one it should be 9. However, both seem to get assigned IRQ 0.

The output of lspci -vv -xxx -s devices is shown below. Does anyone know what to do next? Is there a way to tell the PCMCIA modules which IRQ to assign to the cardbus bridges, instead of trying to find it via the BIOS or whatever way is being used standard?
