I tried 2.6.34. I have jack 1.9..5 installed. I was able to use
rhythmbox to play mp3s. I could not use the echomixer app. It complained
about a channels mismatch.

My goal is to be able to plug in a MIDI keyboard, or USB guitar
interface and play along with songs etc.

I plugged in a MIDI keyboard, "/proc/asound/cards" showed the keyboard
was recognized. The keyboard has a USB and MIDI interface.
I am not sure if they both work at the same time. I had the MIDI cable
plugged into the Gina3G, but I could not tell if the keyboard was
recognized.
I compiled csound5. When I engaged it the system immediately froze and
started spitting out:
