If you boot with BootX (which you *can* *not* use with the Pismo), OpenFirmware
takes care that the CardBus Bridge is initialised properly (but the kernel still
get a wrong number of pci busses on the Wallstreet/Lombard...). If you boot with
yaboot, some registers in the bridge contain bad values. I tried the stock
LinuxPPC 2.2.18 sources a few days ago, and they *still* need the patch. I did
not try the kernel-pmac rpm though, but if your box does not detect the IRQ,
there is no other solution than building a new kernel.

You just have to patch your kernel sources, as decsribed on my web page (see
http://www.mpifr-bonn.mpg.de/div/iri/Archiv/LinuxPPC/PCMCIA.html, just follow
the instructions in the section "Kernel Setup").

It *might* be possible for you to use the kernel-pcmcia-cs-2.2.18-4h.ppc.rpm
package. If it does not work, you should build your own pcmcia stuff. As pointed
out in the "PCMCIA/CardBus" section of the web page mentioned above, on the
Pismo you should use the stock package from sourceforge *without* any additional
patches. You *must* change the pcmcia config files afterwards, though.

Hth,
