I'm dealing with the same problem although the computer is a Acert Travelmate 5530-704G32Mi (AMD RM-70, 4 Gb RAM, Ati Radeon HD 3470XT).
I have tried all drivers (radeonhd, fglrx and ati) but none seem to get the monitor going.
The best results have been with fglrx - I can hear the sounds of gdm and gnome (login sound etc) but the screen stays blank.
When I tried to switch to the vesa driver I got the error message "no screens found".
