My experience with Acer TravelMate 5335 (video Intel GMA 4500M) and ubuntu 11.04:

SOLUTION 1 (bad):
renounce to graphic acceleration and add "nomodeset" into boot (typeing "e" on grub start) or in GRUB_CMDLINE_LINUX_DEFAULT option into "/etc/default/grub".
at least you can boot without an external VGA monitor and try to solve

SOLUTION 2 (quiet bad):
try to install previous kernels like 2.6.35
(there is an italian debian experience at

SOLUTION 3 (less bed):
add the following commad into "/etc/rc.local" :
setpci -s 00:02.0 F4.B=00
The kernel bug remains still there but your monitor will turn on boot before loading x server.
But the game "tux racing" turns again the monitor off. Hibernating too (someone say, haven't tried yet)

I don't know if it is a linux bug or an ubuntu bug, surely this interests debian distributions too.
sorry for my english.
good luck.
