Hardware support is a function of the installed kernel. The newer the kernel the more hardware that is natively supported. Having the newest stable kernel gives you the greatest possibility of success. Try the new beta release, at least as a liveCD, to see if your hardware is all found and functional. If it is, install it, report any flaws, (it is a beta, so there will be some) and install the various DEs you wish to try.
If some part of your hardware is not recognized, or functional, report that fact, so we can try to find out why, and correct that condition. If no one reports flaws, no one else knows they need to be fixed.
I'm here now, because I reported a hardware problem during the 2007 beta testing period, and offered to test any possible solution. A number of things were offered, tested, and the results reported. By the time the final release arrived, it installed on my hardware like it was custom made for it. (which it was, in part)
If you want to see that future PCLinuxOS releases work properly on your hardware, this is your chance to do something to make that happen.
