You'll only need to rebuild your kernel if your DSDT changes and is still
buggy: for example, if Samsung updates their BIOS and you upgrade, and
they've changed the DSDT but not fixed the bugs that the ACPI subsystem had
problems with.

The initrd method is only adventageous if you are in the process of fixing
your DSDT and you'd like to test different DSDTs and don't want to recompile
your kernel each time. The in-kernel method is actually better for me; that
way I don't have to remeber to append the DSDT to the generated initrd.

The initrd method is no longer used for technical reasons I don't remember
exactly.
