No, it doesn't? In the above-quoted output for the udi, there is no
'linux.sysfs_path' key.

This is hal output for an unrelated udi. linux.sysfs_path is a generic key
name that appears on *many* udis - the question is whether it's present on
the same udi that also matches
<match key="info.category" string="laptop_panel">
The one above does not.

It will also break backlight handling for all other users, so this isn't a
patch that we can include in the archive.
