intel 5100 wifi - not detected in Beta 2, can I get it working?

I have a laptop with an Intel 5100 wifi adapter in my laptop.   (I think it is 
5100, might be a 5300 if I ordered the other option, but either way the same 
driver should work?)   I loaded the Beta-2 live CD, but was unable to get this 
to function.  Nothing in dmesg even indicated that the adapter is detected.  
Is there something I can do to the live CD to make this work?   Do I need to 
do a full install and enable something?   

I have been unable to find much about this by searching, apparently Daniel is 
working on support.   It seems that the iwn driver could work, but I can't 
find any status.   

I'd offer to help write the support if I could find enough documentation on 
how this card works (I haven't done much driver work, but I think I could), so 
pointers in that direction would be welcome too.
