Check out some distro's. Most of them have a hardware compatibility list on their sites:
For example:
Suse Linux: Hardware Compaitibility Site
Choose a distro which suites you:
http://www.linuxiso.org/
http://www.linux.org/dist/
And check the following as well:
Linux Hardware Compatibility HOWTO
It's not important which brand your hardware has; the chipset it has has to be supported and the thing will work. As a guideline you can say that in Linux it's the OLDER hardware that's better supported then the newer, because there's been more time for someone to write a driver for it
