Do I need Intel drivers for a Corei5 system?

Sorry to have to ask this, but I'm getting in over my head and I don't want to waste a ton of time wandering aimlessly.

I've upgraded to a new Asus motherboard with a Core i5 2600 processor. Everything seems to be running fine under 11.04, although 11.11 refuses to install for various reasons, but I'm content with 11.04 for now anyway, but so far, that's the only sign of trouble except for last night....

I installed X-Plane 9 from my disks and X-Plane 10 from the web site demo (http://x-plane.com/) since Version 10 apparently handles multi-core CPUs better. That took about 4 hours :-( since it covers 6 DVDs.

At any rate, starting the X-Plane 9, The loader seems to be OK, then it switches to a distant terrain view and begins to zoom in on your aircraft on the runway. Everything so far seems normal.

Once the camera switches to cockpit view, the graphics goes screwy. People with Corei5 Macs report no problems, So.....

That leaves me wondering if I need to install a driver to properly handle the Corei5's internal GPU. I'm not using a video card for now since the Corei5 has so far outperformed the system it replaced which had a Geforce card in it, so I'm happy that it's an improvement.

I went exploring and came across this page for Intel Linux drivers: http://intellinuxgraphics.org/2011Q3.html

However, I now feel overwhelmed. Do I install the Kernel driver, the 2D driver, the 3D driver, or do I need all of the above? I'm guessing libdrm is probably for handling the Digital Rights Management during DVD playback, but the page doesn't explain that; and what is libva and do I actually need it?

I gather, by browsing through the Documentation pages, that this stuff is really oriented toward developers and perhaps a still-wet-behind-the-ears desktop user shouldn't be playing there, but it wouldn't kill Intel to be a little clearer about what these packages are for and in what combinations.

I've downloaded them all anyway, but I'm reluctant to screw up my system by trying to install them without getting some advice first.
