Nothing. I've been driving to and in Austria for 25 years and have never done anything special with tyre pressures other than pumping them up for the long fast drive through Germany, then dropping them back to normal when I've arrived.

If this is your first time, what you WILL notice is that you lose power in a naturally aspirated car - you're down to 75% of engine power at 6000 feet IIRC, and I can assure you it will be obvious! If you have a turbo, in theory it will just work harder and give you the same power, but in practice (and from experience) you will still notice a drop.
