Nothing really different between etch and lenny.

You're right, but unfortunately, there doesn't seem to be an easy way to
preserve a sane solution which wouldn't cause any regression for users
of different BIOS versions : http://marc.info/?l=linux-acpi&m=124082753813945&w=2
So I guess we're stuck with having to manually tweak boot params until
something better is devised.
I'll try and close this report when a definitive answer is provided in
upstream list (probably soon, then).
Thanks for caring.
