Many thanks for your help!! :) I fixed the warnings, if all works good I'll post the fixed dsdt in the proper acpi website section. I added an useful patch (made my Daniel Drake, a gentoo dev) to fix the annoying LID problem that affects a lot of Dell notebook models: the lcd monitor doesn't come up when the lid is reopened.
