The patch initiazile EC(s) as the really first device(s) (but I am
perhaps wrong, since I read it really quickly though), which break
acpi "spirit" imnsho. The EC is a child of other devices and you
have to be sure that those devices are initialized before EC (even
though that is done by BIOS at POST already, due to legacy access
in some laptops).

Please do not use acpidmp, but iasl instead, or send a raw dsdt.

Look at http://acpi.sf.net/ for how to get iasl.
