It's described in detail in "The Garmin GPS Hacking Project" (link from
Peter Bennets GPS site) as a "feature" of the version 2.x software, which
was the latest version at the time. The more expensive GPS 90 was a black
GPS 45 without the speed limit (160 km/h = 100 mph) and with an airport
database and a higher price tag. Maybe they removed the limit from later
software revisions.
That would give us a new way of determining the software version: Just
strap the GPS to the bike, go flat out, and see if you still get a
reasonable readout!
