RE: [PATCH] cardbus: revert IO window limit

[Mallick, Asit K]

I am trying to find the register information. 440MX is an integration of
440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk should
cover the ACPI and SMBus related I/O registers. Is there a pci dump for
this machine?

Thanks,
Asit
