I agree, but what about the not so ideal real-world? What about closed source 
drivers? Who is going to educate closed source driver writers to inform the 
kernel about their memory requirements early enough? And how long will this 
take?

I think at least as an interim measure it makes sense to have a sysfs value. 
Or discourage closed-source drivers even more.

I prefer open-source gfx drivers and don't need extra pages allowance, but 
that might not hold true for everyone.
