So, it goes without saying, but this is a lot of code to send at once, 
and a lot for one patch, and it would be relatively easy to break this 
up by test function.
Nevertheless, I'll try to give a complete review...

This should probably resemble the other is_*_supported() helpers.

I'm kind of curious what the point of the alternation is here; not that 
there's anything wrong with it, but it seems a bit orthogonal to the test.
At least I presume the two conditionals can be merged into one?

This could just be replaced with ARRAY_SIZE(input_buffers) everywhere 
it's used. On the other hand, the "63" everywhere is not great either; 
it'd be nice to replace that with ARRAY_SIZE where possible. It also 
took me a bit of a minute to realize that this test was overlapping 
every buffer range, not necessarily a bad idea, but could use a comment 
I guess.
Also, what is the point of this "bindless" test?
