[SATLUG] encryption

Due to loss of private health information through laptop thefts the UT
system has mandated that all laptops and portable devices be encrypted,
or have them be surplussed.

I have a few questions concerning those of us who use Linux on their
laptops:

1. is there a noticable performance penalty (esp. on slower laptops) 
when encrypting the entire disk, incl. the operating system?

2. would it make sense to only encrypt the /home partition?

3. What Linux software can you recommend to encrypt a disk or partition?
any pros/cons?

4. Any experience with self-encrypting laptop drives?

Thanks for any feedback!
