Actually I did use modprobe, but modprobe uses insmod and the error message that
came up was from insmod. In my confusion, I mis-spoke.

I get similar, but not identical results from lspci -v. I don't know
if the differences are significant.:

 00:02.0 CardBus bridge: Texas Instruments PCI1130 (rev 04)
	 (Subsystem line is missing)
         Memory at 10000000 (32-bit, non-prefetchable) [size=4K]
         Bus: primary=00, secondary=20, subordinate=22, sec-latency=176
         (Memory window lines are missing)
         I/O window 0: 00000000-00000003
         I/O window 1: 00000000-00000003
         16-bit legacy interface ports at 0001
	
Note the I/O window is rather different, and a different TI part #.
It seems bad to me to have two windows mapped to the same address range,
but what do I do about it?

Thanks.
