Answer 1

easy... first, click on switch no. 1 for about 10 minutes or so. then turn it off, click on switch no. 2 and run like hell to the room with the lamp. you would know which switch it is by:

1. if the light is on, then it's switch no. 2
2. if the light is off, and the bulb is warm, then it was switch no. 1
3. if neither of the above, then it's switch no. 3

Answer 2

Click on the first switch and wait a couple of minutes. Then turn it off, click onthe second switch and run to the other room with the lamp. you would know which switch it is by whether the light is on, off, or warm.
