I've tried some newer kernels. Still having problems with the echo 3G.
This is kernel version:
2.6.32.13. The above patches posted to the linux kernel list seemed to
get rid of the crashes, but evidently did not go into the main kernel tree.
Indeed. I've just checked 2.6.33 and the patch isn't there. It's in 2.6.34.

If you need 2.6.32.13 you can apply the above patch to the kernel tree or
download ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.23.tar.bz2,
otherwise just use the latest kernel.
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:
