The conclusion would seem to be, 512M ( aka 4x 128)
should work according to spec, but you might get lucky
with certain 256mb dimm's. The reasons why this luck occurs
are currently unknown :).

I guess it's almost the same situation as with the symbios
895, of which I have an alpha compatible version.

The memory in my 164SX is (iirc) Dane-elec's DP133-07232,
which won't help a lot, because dane-elec doesn't seem to
publish spec's. And I ain't to sure that they keep the layout
of that dimm the same.
