[PATCH 0/1] [Oneiric] S3 early resume debug via keyboard LEDs

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Add support to debug early resume hangs by flashing the keyboard LEDs
three times.  This should help us to see if S3 has successfully
transistioned out of the BIOS to the realmode path of early resume.

Add kernel parameter acpi_sleep=s3_leds to enable the s3 debugging
option.  This can also be enabled by writing 8 to
/proc/sys/kernel/acpi_video_flags.
