Hello dear developers,

when loading pdc202xx_new on a 2.6.9 kernel with ACPI on the moprobe
 call will never return and prints many errors [0].

The controller is a Promise Technology, Inc. PDC20270 (FastTrak100 LP/TX2/TX4) (rev 02).

If loading the driver without the forced option, it says deactivated
by BIOS.

On the other hand, when loading with apm onlyi and enabling forced, 
it works fine [1].

So my questions:

- Why does it fail with ACPI?
- Is it possible to fix that? If, how?
- Is it possible to make forced enabling a module option?like force_against_bios=0|1
- Where in which bios (controller/Mainboard) should one activate the ports?

Greetings, 

Nico
