linux-headers - which to install?

[turboscrew]

I very probably have to compile some drivers for my Mint 11, and I recall (from Debian) that some linux-headers package is required.
I also remember from Debian that there was a pseudo-package "linux-headers" that always kept the headers updated with the current kernel version.

Is linux-headers-generic similar pseudo package? It somewhere said something about LATEST headers.
What's "pae"?

My machine is desktop, and the most probable driver requiring compilation is the webcam driver.

I mean, there seems to be 22 "linux-headers"-packages altogether.

pae headers, if I remember right is if you have more than 2gbs of RAM on a 32bit system, more than 1 core on your CPU(HT counts even if it's only 1 core).

If you can say yeas to at least one of these you need a pae kernel.

I had to use a pae kernel on my AtomCPU because of (HT)

Aha, thanks, wyrdoak, that pretty much says it about "pae".

Does anyone have answers to the other question:
Is there such a pseudo-package that is essentially "linux-headers-current-kernel"?
Or which linux-headers -package(s) I should install?
