You can help me fill the acpi4asus wiki [1]. If we manage to get a real
list of laptop where we should not write in WLED/BLED, then we can
try to implement a black list.

WLED/BLED/WAPF never worked well, mainly because the behavior
seems to be completly inconsistant between laptops. You may try to
ask Asus about that, but they never answered to me :/. But again, the
wiki could help us, we just need to find out how  HWRS, RSTS, SFUN
and WAPF really work.
