I downloaded the driver software from Broadcom and rebuilt the driver 
(has to be compiled against kernel).  That all seemed to go OK.  
However, the driver fails to load:

[root at moby root]# insmod bcm5700
Using /lib/modules/2.4.20-18.9/kernel/drivers/net/bcm5700.o
/lib/modules/2.4.20-18.9/kernel/drivers/net/bcm5700.o: init_module: No 
such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg


There is nothing in the messages syslog from the attempted load.  
/proc/pci sees the hardware, and so does /proc/iomem

 From my very limited understanding, it seems like the driver doesn't 
know where the hardware is.  Maybe the driver is really for a pcicard 
version of the chipset, or maybe it's a configuration problem.  Since 
neither IBM nor Broadcom are willing to provide any information, I'm at 
a loss.  Any suggestions are welcome.

Thanks for looking at this.
