I reworked now the 1.14.3841212 driver and cleaned up the code, but I'm 
still not able to start the pvrsrvctl since it seems to miss the PDUMP 
support in the kernel.
Do you or anybody else know how to enable it? When I add the defines 
that are required for pdump I get the following error: "implict 
declaration of function dbgdrv_ioctl". This call is located in pvr-drv.c

I will share/push my code to a branche in our repo, when I got a running 
demo and I will add some infos to the wiki, how to set everything up.

We should also add some more information, how to setup all the devices.

I think the DDK's use a µkernel in the gpu that is loaded during the 
boot process that might be also a reason for some issues.
