The problem with these chipsets in their day was that linux 2.2 had pretty
simple memory management - it just loaded as high as possible, regardless of
whether the memory was cacheable or not. Does anyone know what the state of
play is with 2.4 ? Is the memory management smart enough to always use cached
ram in preference to uncached ram?
