Hi again,

Sorry to follow up to my own message.  However, I received a couple of 
suggestions privatly and was able to get the modem card working!

It appears the card was confused being accessed on addresses above 0x4000 (I 
found a note about it only decoding the lower 10 bits, see also the strange 
CCR register values in my original posting).

To get the card to work I did the following: (i) Set the cardbus IO window 
offset to 0x10000-0x4000+0x3f8 and (ii) set the PC card IOBASE to 0x3f8.  
This causes the card to be addressed at base address 0x3f8 rather than 0x4000 
(as assigned by rbus).

I suspect other values than 0x3f8 would work as well.  The 0x3f8 was used 
because it matched the selected config table entry in the card.

Since this modem uses the Lucent/Agere Venus chipset, it is likely that the 
above solution may help with other non-working modem cards as well.

Thanks to Christos and Garrett for helpful comments.

Thanks,

Sverre

PS I've attached a (much shortened) dmesg output.
