Interesting. So regular XP is certainly working b/c of a
Dell platform-specific driver. Though it may still be a bug
in the Dell BIOS that the platform is depnding on that.

This works because of the _DSS, and would still work
if you excluded the Notify?
This is an exciting discovery indeed!
Perhaps we can get the acpi video driver to invoke _DSS
on lid events (or for that matter, on S3 resume)?
