I get conflicting results.

If I import it into an x-y location, I seem to get the behaviour which
you describe. OTOH, If I import it into the appropriate lat-lon
location, I don't have any problems (the only areas with negative
altitude are where I would expect, i.e. Holland).

NB: I'm running the latest 5.0 CVS, and there's a bug where it ignores
the rows/cols parameters if you specify N/E/S/W (I've fixed this, but
CVS is down right now so I can't commit it).
