Does the patch in appended message fix that?

Sort of. The 4K cardbus windows are working fine for non-x86 architectures where all IO resources are usually well known and added to the resource tree properly. However, on x86 there are sometimes "hidden" system IO port ranges that aren't reported by BIOS, so the large (4K) cardbus windows overlap these ranges.
Actually I don't like reducing CARDBUS_IO_SIZE to 256 bytes, because we lose an ability to handle cards with built-in p2p bridges (which require 4K for IO), plus it won't fix Sony VAIO problem.
Tero and Mikael, can you try this one-liner instead?
Ivan.
