by trying things like the following for a search
palm site:weather.com
results include
http://www.weather.com/services/pda/...?from=pdaindex

a relevent snip says

"All other Palm devices can surf current conditions, forecasts and weather news by visiting www.Palm.com and downloading The Weather Channel's web clipping application. A modem or other wireless connection is required."

note, this does not seem to indicate maps in motion on palm exist, but it is the BEST way to find such specific info on websites.

(it's also the VERY BEST way to get relevent results from microsofts knowledgebase) i.e. search for
problem site:microsoft.com
