If this is _REALLY_ a nvidia problem, I could paste the dump to NView
forum and ask the nvidia developers for help with the nvidia driver (But
I guess, I will not get help there).

It really depends what is hidden inside the binary-only portion. If they try to enable/disable interrupts in there, for example, then the driver is going to be unreliable. If they provide accessors for that kind of operation in their 'open source' wrapper, then that shouldn't be a problem as they will link against the versions modified for Xen. Looking at the functions exported by the source wrapper might give you a clue, or try 'objdump -d' on the binary-only portion and grep for things like cli, sti and popf.
