More information for those who care. Intel introduced extentions that allow
for page sizes greater than traditional 4K with the pentium processor (4Mb).
Unfortunately, while the athlon supports these extentions there are issues
with memory corruption when used in conjuntion with AGP. This ammounts to
a nasty harware bug that only exibits itself I think in one circustance
of table flushing but this may be incorrect. Anyway, the stopgap is
as chris mentioned mem=nopentium or turning off AGP.
