I bought a notebook last week with a Mobility 5870 and of course stress tested it to find out if it worked fine before the return window ran out. I quickly found that with Catalyst 10.3 that it will get the grey lines / screen corruption / black / white screen freeze (it varies) quickly in 3D apps. It's stable with the notebook manufacturer's drivers (9.12-based) though, but I've found that other people are fine on 10.3. I'm in the process of doing an exchange for a new notebook now.
Over the past few days I've done some searches for these grey screen / black screen / stripe / corruption issues with the 5xxx cards. I am surprised to find that there are many posts around the web on a lot of different sites about this. Some news sites have articles about it too. There's even a hotfix to "alleviate" the issue (ie reduce it) for 58xx Cypress-based cards, but it's not always effective.
I'm inferring from this bit of research that ATI is having problems with their GPUs in some way that they can't debug effectively. Notebook graphics chips and desktop addon cards are passing QA testing and making it to customers and then showing serious, unsolvable problems. Replacements seem to solve the issue, meaning it is some sort of hardware flakiness with the graphics card. Some people seem satisfied with tweaking Powerplay settings or downclocking, but that's not exactly a reasonable cure.
Here is a Tom's Hardware article I found that collates info about the problems:

This is the worst that I got from my notebook during testing. It would usually do some flickering before crashing completely and requiring a manual power off. This was a windowed Furmark session, but I initially ran into the problem during some Serious Sam HD. The problem didn't seem to be temperature related either, because it would crash almost immediately sometimes, before it could heat up.
How many here have run into these kind of instabilities with their GPUs? Silent Buddha, I found some of your posts when I was searching B3D.
