trouble waking from S3 on macbook pro

[Andrew Marks]

I am running 9.0-CURRENT w/ a custom kernel.

Is there more suspend/resume info out there than this:
http://www.freebsd.org/doc/en/books/handbook/acpi-debug.html

My Macbook Pro will not wake from S3, and I can't find more info about
acpi_lid, or gpe, or what is missing.

You have mail.
cubemonster# sysctl dev.acpi_lid.0.wake=1
dev.acpi_lid.0.wake: 0
sysctl: dev.acpi_lid.0.wake: Device not configured
cubemonster# tail /var/log/messages | grep acpi_lid

I turned on more debugging and:

Just looking for someone to point me in the right direction to make this
work, I may be headed the wrong way as it is.

Thanks,
