I have finally got CentOS working on my Dell Inspiron 1150 laptop with the internal wireless A/B/G card. After a bit of searching on http://www.google.com I found http://www.linuxant.com . They charge $19.95 for the lifetime license to the driver but it was damn worth it. The install couldnt of been any easier. It even uses the windows drivers and recompiles them to run perfectly with your kernel. I am now able to lay on my couch with no wires with my LinuxLappy! What could possibly be any better then this? LOL, I can think of many things to.  Anyhow, I TOTALLY recomend http://www.linuxant.com .
