I tested various ectype options with this laptop.
I attached the results as a Matrix ectype x features.
Here is the dmi info:
BIOS Vendor: TOSHIBA

System Vendor: TOSHIBA
Product Name: Satellite X205

where the BIOS vendor actually is PHOENIX!
The dump-information as well as my dsdt-information is attached as well.
Let me know if I can do any more tests!
