I read in the handbook (12.13.1) "the acpi(4) driver is loaded by default at system boot and should *not* be compiled into the kernel". Yet I see "device acpi" in GENERIC. Aren't those two things in contrast? Is the information in the handbook outdated? Wrong? Does it mean something different to what I believe it means? What is "options ACPI_DMAR"? What does it do? Is it ok to add "device acpi_video" to a kernel config? bye & Thanks av.
