OMG, thank you SOOOO much. Superuser app finally works!
EDIT: Here's the original Superuser-3.0.7 recovery-flashable ZIP file with dzo's 'su' binary replacing ChainsDD's broken one. I re-signed the ZIP file and flashed it and it seems to work. The Superuser app prompts for Allow/Deny access and apps requiring root access seem to work well.
