Do not forget that several manufacturers may use quite different chipsets
for the same product model. One excellent source of information is a site:
http://www.linux-on-laptops.com/
this is a complex site to weave through. Information coming together in an
unwieldy way, but as I have found out is more manageable if you look for the
laptop make and model that uses the specific card, or a cross-referenced
one.
The reason why this information is usefull, is that in the Linux world the
lack of drivers is quite as frustrating as it is for us - some genius(es)
found a way to use Windows driver INF files to actually drive the card and
make it functional, it's called 'ndiswrapper'. Most things turn out to show
life-signs with some effort, while some simply doesn't work at all. If that
is what you have, even that is good info.
