I'm the satisfied owner of an Athlon XP 2800+ mounted on an Asus a7v8x board, using the latest 1015.003 beta bios, which has worked fine for almost two years. However, I've noticed that after restoring from suspension mode, the FSB frequency doesn't get restored correctly.
To be precise, if I'm using 170Mhz, it always comes back at 166. I don't know if this a hardware or bios problem/bug and if this happens with other chipsets. Additionally, after coming back from suspension mode I notice a low level high pitched sound coming from the speakers, which probably can be a consequence of the previous problem.
