unknown ways. Until that breakage is sorted out, be conservative. I'm not backing this out in current so I can track down the issues. I'm also not backing out the pci parts of this commit because with the old cardbus code they work perfectly as far as I've been able to test. I'm leaving cardbus_device.c in place as well since I anticipate being able to reconnect it when I resolve this issue in head and cvs rm + cvs add on branches can be a pita...
