Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+This is not really a board made by ITE Semi, but it's very
+similar to the ITE QED-4N-S01B board.  The IVR board is made
+by Globespan and it's a reference board for the PVR chip.
