Andre, My macbook experienced this same problem after a firmware update.(Random shutdowns followed by booting to a rainbow screen). I fussed around with it in much the same fashion as you describe until I found a site that suggested zapping the pram several times.
In particular is suggests using the cmd-option-P-R key combination while booting 3 times. On the third time let the system boot through to the desktop. I did this process twice and haven't had any problems since the 10.4.8update. -- cb On 10/8/06, Pierre Sahores <[EMAIL PROTECTED]> wrote:

I had to reboot to get the laptop running OK again. Perhaps just a firmware update to fix, perhaps more...
