I have a very similar problem. When trying to boot Lucid post alpha 3, the display shuts down after start of a boot, and turns on after a wile with corrupted screen (desktop wallpaper mashed up with other colors), and I don't hear the login sound, and can't see and use mouse or panels, icons.....
When booting with nomodeset=0 I can use the system with vesa loaded. The laptop is Acer Extensa 5635G with Nvidia G 105M. This laptop has corrupted EDID. I know that because I was having problem with Nvidia propertary driver which, when used, divided my display to 6 little screens with resolution 640*480. Nvidia guy's said that this was occurring because EDID was invalid and they made workaround for this bug in last beta driver.

Here is the xrandr --verbose while in vesa:
