Hello again!!
I finally found an approach to the driverproblem Vista and ati mob.radeon 9200 that works for ME on my hp/compaq nx7010...

1. Install a fresh copy of Vista
2. finish all installation and personal adjustments......
3. Copy or download from HP site the XP ATI driver install package to your computer = SP30204. Unpack it and it will be found in a "SWSetup" folder. Do not try to install yet
4. Set screen resolution to 1024x768 or higher - this will most likely give you a Black screen on next boot/startup.
5. Restart your computer - most likely screen is black - let computer finish loading, then crash it by terminating power.
6. Start computer again, and choose "safe mode" on startup
7. Uninnstall all/any graphic related drivers / uninstall the 9200
8. Shut down computer
9. Connect the external screen to the laptop - start up normally - funny isnt it- an external screen is OK, but the laptop one isnt.....
10. Vista will annoiunce "found new hardware" - let Vista install any driver it may have
11. Access the SWSetup/SP30204 folder - install the XP-driver . If installation program complains about no driver installed / VGA driver is required - reboot and let Vista have another try- uninstall any driver again if necessary
12. Restart and install driver from program above. All done and working well- restart.
13. on next startup Vista will still complain about your driver and/ or ATI software. Do not attempt reinstall as Vista proposes, decline and check the "dont tell me again" box. Also do this if any compatibillity msg for ATI software is given = Run progr and dont ask again.
14 IF this works for you as it did for me, you will now be running your nx7010 with the staggering old 1680x1050 resolution and no questions asked !!
15. if by any chance it doesnt work- try different similar approaches - no probs as long as you have the external screen at hand.

GOOD LUCK!!!
