Which driver do I use?

When I do a lsmod I get a i915 output. But judging from the fact that this laptop has a hd4000 intel ivy bridge display, I'd expect the module to be i965.. Isn't the i915 for outdated hardware? Looking at the intel x.org feature matrix I can't see the ivy bridge feature matrix displayed there.. How can I get a detailed picture of the support status of intel ivy bridge?

The graphics drivers on linux consist of several parts. They have a part that lives in the kernel and a part that is in userspace. Intel has only one kernel module (I believe) and it's called i915 for all cards.

The userspace stuff for e.g. X has the i915 and i965 names:

$ grep i965 /var/log/Xorg.0.log
[  5236.213] (II) intel(0): [DRI2]   DRI driver: i965
[  5236.228] (II) AIGLX: Loaded and initialized i965

So that explains the confusion. Thank you.
