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?

Some more infos about the panic would be useful. Enable xmon and tell
me what it sayd about the PC & LR of the crash, and the backtrace
(obtained with the "t" command). If you use a recent yaboot and kernel,
you may even add sysmap=<of_path_to_System.map> in yaboot.conf to get
the System.map loaded along with the kernel. This will allow xmon to
display function names as well as addresses in the backtrace.

I saved the following XMON dump...  (already had it enabled and it
dumped me there when the crash occured.)  I have translated it for you.
But I don't have the PC or LR.  I will have to recreate the failure
later tonight after I get off of work.

Also I used this line "sysmap=/boot/System.map-fw" to load the system
map but then I realized you said OpenFirmware path.  How do I calculate
the openfirmware path to the system map?  And would this be dynamic when
I recompile if I just put the file in the filesystem or would I have to
reload it with ybin?  Thanks again for all your help.

Here is the stack trace from "cat /proc/ioports":

vsnprintf
vsprintf
sprintf
do_resource_list
do_resource_list
get_resource_list
ioports_read_proc
proc_file_read
sys_read
