what is required to support a new laptop?

[Eitan Adler]

Hi all,

I recently purchased a Lenovo Y530 and attempted to use some of the
ACPI features (brightness of backlight, etc.)

I attempted to load acpi_ibm but devd reported no events (running with
devd -dD).  What information might be useful to help support this
laptop?

Where are events such as "fn+pgup (brightness up) reported?

http://freebsd.org/~eadler/files/asl.y530.gz - acpidump -dt if this
may be useful.
