dapper regressions on last ibook

[Leonardo Pistone]

Hi all.
I use breezy on a post-july 2005 ibook 1.33, and I'm testing dapper 
flight 3 on it. There are a few regressions on it. One is quite severe: 
a module is not loaded, so the fan is ALWAYS off. Where and how should I 
report these? In launchpad, ok, but what should I write as "Source 
package name?"

In the meanwhile I'm updating the laptop testing team wiki on this laptop.

Thank you for your help
Leo
