I would say to see if you can plug your laptop into the web with Ethernet. Then using YaST, type in madwifi or broadcom to see if the correct drivers don't install themselves.
You may have to add testing or rawhide repositories (or enable them) in order to find the right driver. Obviously, back up your data first !!
There is also another product out there called a wireless Ethernet bridge, which does exactly what it says. It has Ethernet on one end and an antenna on the other.
Sometimes the best way to deal with this is to get a friend or yourself with Internet to download a few live CDs from other distributions such as Fedora 12, or Mandriva or Simply Mepis (test mouse) and see if they don't find your wireless. I had to switch from SuSE 10x to Fedora because the sound alsa would not work with my laptop.
This is why people always are switching distros with Linux all of the time. It is that some codec, function or hardware works better with something else. Unlike M$ or even OS-X, you have.... choices with Linux.
** OS-X isn't bad though, far from it. **
I'm not too sure about this, but if you use a DVD-RW or CD-RW instead of a read only disc, you might be able to do some optimization on the live disc before making the decision to install.
If another distro has no hardware issues, it is the path of least resistance to switch to that other distribution. I usually test at least 2 or 3 distros when I put Linux on a computer before settling on a final choice.
Don't forget to try out PC-BSD 8.0 or Open Solaris. They too have live media and might be a good fit for your machine if some of the other Linux distros don't fit. These are both excellent operating systems.
One other thing, if you do decide to install a distro from the live CD, it may be better to go ahead and download the DVD for that exact same distro because the live CD will only give you a stripped down version of Linux. You can enable online sources to get additional features, but that takes a while.
One of the nice things about Fedora 12 is that you have the option to encrypt the hard drive partition just by checking a box and entering a password. This should be very complex, strong and easy to remember because it CAN'T ever be changed IMHO. Fedora 12 even works with my wireless all in one HP printer using wireless.
While SuSE is one of the better distros, it does seem to have a few more hardware problems and YaST seems to break easily. I'd say try Fedora 12 first, then Simply Mepis then Mandriva (but not Metisse) then the UNIX's that I mentioned.
Don't forget to test the sound, peripherals (keyboard mouse screen), !!! PRINTERS !!! and any other hardware like webcams external drives USB etc as part of the live CD test. This is important.
Let me know how it all works out.
