Oh, true, it's the HAL that differs. I have little hope not to reinstall. I imagine I should replace the HAL file(s) (and kernel?) with those from a non ACPI installation, and I dont' really know if even the recovery console lets you do that. I doubt. Probably installing the hdd in another machine...

Well, if anyone has an idea on how to do this, you're going to have my deepest gratitude Otherwise, you'll have my gratitude while I reinstall. Where's my installation CD?
