Hey Saridnour,
In regards to your bluetooth service pack, unless has had any negative affects, I really believe that the Priority 256 registry entry should be in the ROM. Reference:

I really couldn't get my bluetooth to work until after I had that setting in place. (using MSI FS300)
If not no big deal to me, but others may need it also.
