Comment(by fhn):

 I observed the same problem on my machine.
 While reading through the source and the docs i found two things:

 1.
 In via_lvds.c in ViaLVDSDFPPower(...): the mask for turning the DFP pads
 off should be 0xF0, not 0x0F in my understanding.
 Maybe someone with more experience in graphic drivers should have a look
 at this.

 2.
 I don't understand why we change the pad control bits at all since the
 pads are switched on/off according to the PMS state by the hardware.
 So i disabled the execution of ViaLVDSDFPPower(...) in ViaLVDSPower(...)
 and the problem with the wireless card are gone.
 Of course this is only a workaround, not a solution.


 I attached openchrome_741_hp_2133.patch, which contains both changes.
