Interesting.
I'm running RELENG_5 on this machine, is there any way that I could test
any code? In particular the acpi_video DPMS patch you mention; is that
compatible with 5?
I've got the following ACPI modules loaded:
4 1 0xc09f3000 4d98 acpi_video.ko
5 16 0xc09f8000 53828 acpi.ko
6 1 0xc0a4c000 25b4 acpi_sony.ko
The acpi_sony one I (trivially) ported to 5 myself.
