Sorry for a bit late reply, it was a long holiday in Thailand and I was totally offline for few days :)

I'm not sure whether this is about ACPI or not. As far as I tried, without Daniel's patch the cardbus would not work, no matter what boot params specified (I've tried acpi=on, acpi=off, acpi=on pci=noacpi, pci=biosirq).

With the patch, it seems to work fine, at least with "acpi=on" and "acpi=on pci=noacpi". I haven't try the others. I'm now using 2.6.5-mm4 (that includes the patch), boot param is "acpi=on". It produced some warning about "pci=usepirqmask" but the cardbus controllers work.

If you want me to test anything on this, please let me know. Below is dmesg with "acpi=on".

rgds,
kitt
