I am running the Full PCLOS 2010.7(fully updated) kde version on my Compaq SR1303WM machine with no problems.
Its a 2004 model that had 512 MB of RAM ( just recently updated to 2X1 GIG sticks RAM)
Until I installed the New RAM running the live CD was kind of a pain, but still managed to get PCLOS installed
and from there all was well.
