I greatly appreciate all of the work you put into maintaining this 
stuff.  nvidia certainly doesn't make it easy.  I support approximately 
600 desktops, most having nvidia GPUs.  It would be much more difficult 
without your tools.  I'm able to use nvidia-detect and puppet together 
to make sure the correct nvidia packages are installed.

In the case of the K1 that does cause a slight issue.  nvidia-detect 
returns a '6' code, which equates to the (currently) non-existent 367xx 
packages.  After your information, in puppet I'm treating '6' and '1' 
the same and installing kmod-nvidia.  But I'm not sure what the best 
approach is.  I understand you don't want to return a '1' for the K1 as 
it's not really using the 'current' driver.  But installing kmod-nvidia 
is the correct solution for now.  But returning a package that doesn't 
exist isn't ideal either.

I'm sorry I don't really have an answer (other than my own work-around), 
but I wanted to make sure you're aware of the issue. Not sure there are 
enough K1 cards out there to worry about.  I only have the one, so you 
don't need to make sweeping changes on my account.
