Not really since nvidia RAID is driver-based you're using the Linux software
RAID implementation regardless of the way you configure it. The only
difference is the on-disk format (and the fact the BIOS can boot from the
nvidia format, but not the Linux-native format) and that the Linux format is
a bit more flexible.
I'm not sure, but I suppose the Linux software RAID driver should be able to
mount the nvidia format, even when the controller in use is not
nvidia-based.
