Cardbus issues on TiBook

As some of you may know I am trying to get an IBM microdrive working on
my TiBook.  I know there is an issue with irq's which I am trying to
work out but I have run into another issue I don't understand.

I get the following message in my startup:

kernel: Can't get bus-range for /pci@f2000000/cardbus@1a

I rsync'ed with Ben H's kernel recently and I found that the ioports and
memory ranges I had set for cardmgr were not working anymore.  So I
started changing them.  In my efforts to find ranges that worked I found
that "cat /proc/ioports" would result in a segfault.  From what I can
tell it is running off the end of the buffer in vsnprintf?

Before the Cardbus modules are loaded "cat /proc/ioports" works fine.

So my question is, what does the above message mean?  It is something
which is worked around later, or could it be the root of my problem?

Thanks,
