Well, I don't remember if that's me.
But I have an acpidmp for a toshiba M30-404.

After doing something like this:

ducrot@neptune:~/acpi_hack/toshiba-M30-404$ ../pmtools/acpidmp/acpixtract SSDT > ssdt < acpidmp
ducrot@neptune:~/acpi_hack/toshiba-M30-404$ iasl-20041203 -d ssdt

and the resulting ssdt.dsl will contains the processor object.

So all you have to do is to add something like that:
External (\_PR.CPU0)
onto the dsdt.dsl in order to get rid of those errors.

A corresponding diff is:

--- dsdt.dsl	2005/02/28 18:21:07	1.1

I dont know for the toshiba acpi driver.  But there is for sure support
for the acpi_video driver in this dsdt.

It may be fine to test if by chance acpi_video work.
