assume there is still no power management for evergreen, just the older cards? Noticed that while the open source driver can play flash videos just fine on the new 5470 card, the fan runs constantly on the laptop. Installed the fglrx driver and dead silent.
yeah, welcome to the world, bro. Getting a radeon laptop with newish graphics card means no 3d, no 2d accel, no xvideo, no power management. It means it will run dead slow and drain your battery like there is no tomorrow.
Best way is to use Windows and put Linux under a VM, then prey Linux driver will be in good shape in a year or two. Trust me, that's the only way out.
Think of it that way: this is no reaons to buy a new radeon laptop because you can never use it. And when you finally can it is long gone obsolete piece of grandma gear. You should have bought an Intel integrated graphics at least it keeps your battery going, which is the number one reason for a laptop, then it has basic 3D and good x-Video support so at least it is USEFUL.
