If these should work, then there is another bug. The default for rc.conf
is 0xd0000 and the default for pccard.conf is 0xd4000. These values would
probably work, if they were indeed used.
BTW: Is there a userland utility to map all resources used and/or bus
tree? Something like Windows 9x device manager. This is something I'd like
to see, and would surely help people with hardware conflicts.
