Actually now I know exactly what the problem is. The problem only occures when I insert a 32 bit Cardbus card. With regular 16bit PCMCIA cards its fine. So, the above mentioned issue isnt an issue anymore, as 32bit cards are handled by hotplug.

This is what I see in /proc/ioports (only the necessary parts)

1000-10ff : PCI CardBus #01
  1080-109f : Sony Programable I/O Device

This obviously shows that Sonypi is under the PCI CardBus's range, hence when I have a card inserted, sonypi is overruled. My WiFi card is a 32bit card, and I wouldnt like giving up on that.

There was some discussion going about a similar (same??) problem, but for an earlier kernel. There was even a patch, but again, for an earlier kernel.

If anyone has an idea, please share.

Thanks
