So let me see if I understand this...

Nowadays, the world (or at any rate, the important part of it, i.e. X.org)
thinks that Kernel Mode Switching (KSM) is the Right Way to do this stuff,
and that it is preferable to UMS, correct?

X.org wants everybody to move to exclusively using KSM (?)

FreeBSD has implemented KSM in the kernel, but _only_ for Intel graphics?

Gallium requires KSM (?)

Nobody has coded any Gallium drivers for any Intel graphics chips (?)

(Please excuse me if I say that, as a person who knows nothing really about
any of this stuff, it seems to me a most perplexing state of affairs.)
