That might have been me, as I am using the same option and I posted about it a
few days ago. Yes, it works for some cards, that are unsupported, etc. I also
have another laptop, that has a Centrino CPU and the infamous Intel 855 Video
chipset that comes with it. That needs another kind of solution, which is a
video post tool that wakes video up. You can do the following. Try to suspend
your machine and then resume. Does your machine comes back alive, except the
Video. You can check the led activity on your laptop, or even better, after
resume, try to SSH into the laptop. If you get to it, it is up and running,
besides video. Then, you need some tool, program to wake your video up.
However on my Vaio picturebook, it wont work, as the machine will not wake up
at all. No SSH access, etc. In that case, I do need the above mentioned boot
parameter. It all depends what hardware you have. You might browse for it on
google, or try www.tuxmobil.org for reviews.
