I think it's just module 'video' . I was grepping lsmod for acpi.

RE: the brightness keys affected by kernel acpi: is there any way to just blacklist the specific module(s)? I see CONFIG_ACPI_VIDEO can be a module, which happens to be how my .config (of the running kernel) looks. 

Thanks,
Jim

To be short and sweet: the kernel ACPI video support is fubar before 2.6.20.
Remove it, and all will work.  ibm-acpi is not to blame in this particular
issue :-)

Thanks to all the *60 owners that are helping track this down.  Note  that
not all questions surrounding this issue are answered yet.  We don't know if
a quirk (or ibm-acpi interference, if the API allows that) is needed to
disable kernel ACPI video handling for some ThinkPad events, for example.
