I re-write a patch for NEWCARD.
New patch is,
- detach children of cardbus/pccard devices at suspend time
- probe and attach children of cardbus/pccard devices at resume time
- pccbb devices are suspend/resume
- cardbus and pccard devices are suspend/resume instead of detach/attach
Currently, I'm using this fixes on my NotePC and there is no problem.
