I seem to recall the reason for this being the amount of 64-bit unclean
code that is out there.  I recall someone telling me that an Alpha
running linux spends most of its time trapping invalid memory accesses
and correcting them.  I suspect the only reason ultrasparc isn't bitten
a LOT more by this is the 32-bit compatability.
