Here an extract from lspci -v :

This post is saying that, on another netbook (for comparison), F13 
finds the wireless (on an Acer AspireOne netbook), but F14 RC3 does 
not.  So it seems that there's something different between F13 and F14 
in respect of wireless support.

I'll post back with details of this other netbook, Acer AspireOne, too.
