Pavel's fix isn't really a fix, it's more a work-around. If we keep increasing PCIBIOS_MIN_CARDBUS_IO until we hit 0xffff, everyones system stops working.
The problem there will be that there's some IO registers between 0x4000 and 0x5000 which the BIOS wants access to, but the kernel didn't know that they existed.
In any case, 2.6.3 does not contain the patches for CB1410, so chances are that your problem is already half solved in 2.6.5.
Ok, so the action plan is:
- set 0xc9 to 0x04 for CB1410 (and others?) - find a reasonable solution to the latency timer, maybe just setting it to 0xff when we detect the bridge.
