Well, the ACPI sysfs conversion is not finished yet and some user space tools still use the ACPI procfs. The schedule of removing ACPI procfs I/F will be changed to Jan 08. I'm about to send a patch to update it.
I'm not sure if the button sysfs I/F is already finished. We'd better make a double check. :)
Thanks, Rui

The button driver uses acpi_root_dir which won't be available if acpi is removed this month. That would lead to errors, I think.
