When a new kernel is installed or booted, the driver is actually rebuilt against it automatically.
This is a 20 minute presentation, complete with an example package. There is a video of the talk in OGG format. It will be uploaded to the Ubuntu Dev video channel soon (in case you don't want the 1.4G file I have).
Have fun, and please don't hesitate to ask any questions.
NOTE: I am in the process of uploading the ogg, so be patient:

UPDATE: Here's a smaller file. I hope the quality is good enough to read the projector:

Thank you for the nice presentation. May I upload it to a video sharing site? Will it be a problem
