[nvidia-detect] amd64 only cards on i386

[Floris]

Dear Debian Nvidia maintainers,

If someone with an i386 installation run nvidia-detect with a Tesla V100  
or Titan V card (amd64 only cards) the output message in nvidia-detect is  
confusing/ wrong:

$ nvidia-detect 1d81
Checking driver support for PCI ID [10de:1d81]
Uh oh. Your card is not supported by any driver version up to 390.12.
A newer driver may add support for your card.
Newer driver releases may be available in backports, unstable or  
experimental.

These cards aren't supported on i386 installations and likely never will.

Is it an idea to split the *.ids files in /usr/share/nvidia into:

nvidia-amd64.ids
nvidia-i386.ids
nvidia-armhf.ids

and modify the nvidia-detect script so a user get a message like:
Checking driver support for PCI ID [10de:1d81]
Uh oh. Your card is only supported on amd64.

Maybe we can also check the CPU if a 64 bit installation is possible and  
give an advise to switch to amd64.
