It's actually set to force_ht, so it sounds like some blacklisting is
now stricter than it used to be. However, given that acpi=force seems to
work, how about just doing the following?

ACPI: Remove old blacklist entries

The kernel has a set of blacklist entries that disable ACPI functionality
on various machines. These all seem to date from pre-git days and most
have no indication of what they were meant to fix. Let's work on the
assumption that we've fixed whatever it was that was broken before and so
remove most of the entries.
