Z600 screen restore

Hi,
I have a Sony vaio Z600-hek (same as US model Z505). Which I've been trying to get working with ACPI for a while....

On S3 restore the screen would power up and flash briefly and then power down immediately although the machine was now up and running.

using "acpi_sleep=s3_mode" makes no difference. "acpi_sleep=s3_bios" causes the machine to crash on s3 restore.

but if I comment out the two tests:-

#       testl   $1, video_flags - wakeup_code
#       jz      1f
and
#       testl   $2, video_flags - wakeup_code
#       jz      1f

the machine restores from s3 successfully and the screen powers up... so that appears to be the area of the problem...
any suggestions what the 'correct' fix for this would be?

Cheers,

Ivor Hewitt.
