Well, I recompiled the kernel and the mismatch message went away. However, KDE will not start, back to square 0 (C notation).
Nothing seems to be out there as an alternative to NVIDIA, I called ATI and they told me their drivers do not work with 64 bit, is that true?. Has anybody tried running the opteron system with, say RedHat9 (32 bit). Will the card work there?
