Hi Guys , I have been using this thread for a few days trying to get my hybrid physx working using a AMD6970 & a GTX285 , the post below was what got it running with the latest ATI & Nvidia drivers. (THANKS!!) (please note I DID NOT reinstall drivers, or do anything other than this and that was after I tried both 1.05ff mod & hybridize multiple times and various tests with no success.)
Errors during testing ranged from missing files, to physx out of date and the rather annoying no load on the Nvidia GPU, I folllowed the above intructions TO THE LETTER and now it works fine with no issues. (I didnt install anything accept the mods while following that guide as I already had the drivers & physx installed.)
Also i noticed that there is in fact a difference running physx from GPU & CPU, the game\ drivers automaticaly remove certain effects when running on CPU regardless of how powerful it is or how well it runs, to get full effects the physx MUST be ran from a gpu, this was very noticable via testing as I can actually run the game with physx up full with no GPU & get much the same performance I do using the Nvidia card, it does however look much better using the nvidia card. (shoot stuff with elemental weapons in both setups and you'll quickly spot the difference, also note the difference in movement of cloth, its far more detailed using the GPU)
Anyway, hope that helps, I played several hour so far using the hybird set up & have not had any issues so far.

Also, in case you aren't getting GPU load do the following:
Open this in new browser tab:
Just get the newest Physx from http://nvidia.com/object/physx_system_software.html
and then the hybridize program from the above also.
Install PhysX System Software, then Hybrid mod 1.05ff, then ran Hybridize, then ran the PhysX-HwSelection-set-GPU.cmd file as admin (important).
Then go into your G:\Steam\steamapps\common\Borderlands 2\Binaries\Win32 folder and move all the PhysX_____.dll files except for PhysXExtensions.dll to somewhere else.
Now when you run BL2 you should see load on the PhysX GPU.
