There is a bug in modprobe (now fixed) that cause it to omit printing an
error for the first module, which is the one that actually fails; the
following modules/errors are because these are dependee modules (and not
because of the printed error), but are otherwise irrelevant.

The module that is failing to load is almost certainly the 'video'
module, which is an ACPI video driver. The reason that this module fails
to load can only be that ACPI is in some way disabled, such as by
'acpi=off' in the kernel command line.
