SARS screening consisted of:
It's likely some or all of these will be in effect on your arrival. They are pretty unobtrusive. An actual test for H1N1 (as opposed to just appearing ill) takes hours or days and will not be performed on every passenger, or even every ill-appearing passenger.
If you have a cold or something else mild, take a fever-reducing medication such as acetaminophen less than 4 hours before you land. A person with the flu will still look really ill even after such a dose. A person without the flu may not, and will thus stay on the unobtrusive end of whatever screening is happening.

I'm not sure on this case, but often (on past panic of pandemia) this was done just with a thermal camera (and staff screening passengers). If I remember correctly on some countries (or airports, e.g. Taipei) they still make such screening (just camera and watching people)
Not 100% effective, but if one is very red in front, or high temperature, this person will be examined further. Without lab analyses, it is impossible to distinguish H1N1 from other flu. In any case, such measure is effective also if they block 30% of ill people.
Please [in general, not to you]: if you have flu, do no travel. Do not be egoistic: you will ruin travel, holidays, honeymoons, etc. of many other people. [Note: airlines could also block ill passengers, but although this is in travel rules, I never heard of people blocked for this]
