Resource conflicts on 1st-gen TiBook

[Jeffrey Baker <jwbaker@acm.org>]

After upgrading from 2.4.19-pre to 2.4.20-pre, both benh trees, I
have started seeing resource conflict messages in my logs.  I wonder
if this is related to my crashes.

In 20-pre3, I started seeing this when I inserted my Cisco Aironet
card:

resource conflict with: 80000000..8007ffff (200), name: Apple Computer Inc. KeyLargo Mac I/O

Now in 20-pre4, I started seeing this:

resource conflict with: 90000000..9fffffff (1200), name: PCI CardBus #11
resource conflict with: f3000000..f33fffff (200), name: PCI CardBus #11
resource conflict with: 1000..8fff (100), name: PCI CardBus #11
resource conflict with: 9000..90ff (100), name: PCI CardBus #11

This doesn't seems to make a lot of sense.  How can the CardBus
conflict with itself?  Is this possibly related to crashing?
