Thanks.

Let me then ask another question: since the new Radeon R9-280X, R9-270X,
and R7-260X cards are supposed to be based on "Southern/Sea Islands"
GPUs, would it be safe to assume that they would also be supported?

The "engineering vs marketing names" link on the wiki page should be
updated:

http://www.x.org/wiki/RadeonFeature/#index5h2

And perhaps that table should itself be updated to include the new
Rx-2yy GPUs, especially if those <= 280 can be considered equivalent to
the HD7000 series.

Is Mesa the only issue? Is it likely that distribution packages for
LLVM, Clang, and libclc would be sufficient, or would they require
custom builds as well?

Again, please CC me on any replies.
