Testing the new i915 driver (HD Graphics 4400 and G41 Express)

[Arto Pekkanen]

Yeah, the new HEAD codebase assumes a newer version of Clang from HEAD, 
which is kinda silly.

I mean, the only reason the new Clang is needed is because of this one 
specific warning option in the bxe module -.-

You'd think you could solve this by doing make kernel-toolchain or make 
buildworld (to get a system compiler from the HEAD world), but no: both 
targets fails because the header "yacc.h" cannot be found!

In short: head cannot be upgraded into release system without a 3rd 
party Clang installation.

I've heard rumors that this was fixed in a later HEAD revision, but I am 
not sure which ... and this info would not help me anyway, since I am 
not proficient enough to merge HEAD into the branch.
