Distributors cannot ship fixed DSDTs. That would be to much work. But
there are a lot of Linux Newbies with a laptop that worked so far with
W*. Now they are going to try Linux and get ACPI troubles.
It's far easier to explain them to place a fixed DSDT in a certain
file and to call mkinitrd than to guide them trough a kernel
complilation and installation.
Life would be ways easier for supporters. 

There are people wich benefit from this patch.
Does this patch harm on the other side?

Yes.

Yes.

You cannot always revert to non-ACPI without losing funcionality.

At this point the average private laptop user is left alone. Why don't
we help him to fix his buggy DSDT?

Wonderfull! This maybe helps to come to more sophisticated BIOS
engineer and thus better BIOSs. ;)))

Sometimes i were glad i could fix the programming of my bordcomputer
myself.
