The problem I have of broken display at start-up has nothing to do with acpi. It happens after I for some reason running w* (to communicate with a serial device after its pipe was broken on virtualbox). The machine is multi-boot, and every time I run w* now, I have to e2fsck my boot disk. In spite e2fsck does not show any corruption, if I do it the display is restored. Weird, will investigate further, making copies of the boot files. This was not happening with karmic.
