The other thing I've noticed is that the brightness keys work if ACPI
is disabled, but they don't work if it's enabled.  (That seems odd to
me, but I'm no expert at these things.)

That actually makes more sense -- with ACPI enabled, they're probably
passed to the OS for the software to handle.

Steven is right. To make matters worse, ACPI doesn't specify how these hotkeys should be reported to the OS, so each vendor does it differently. What type of laptop are you using?
