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!

(the following is from the armlinux CVS)

WaveArtist mixer and volume levels can be accessed via these commands:

nn30 read registers nn, where nn = 00 - 09 for mixer settings 0a - 13 for channel volumes mm31 write the volume setting in pairs, where mm = (nn - 10) / 2 rr32 write the mixer settings in pairs, where rr = nn/2 xx33 reset all settings to default 0y34 select mono source, y=0 = left, y=1 = right

                                       bits
