I noticed that all of the keys next to the Enter key would be pressed / released within the blink of an eye. What they all have in common is that they are connected to a column on pin PD6. If you know Soarer's converter and have used Teensy boards before then this might ring a bell:
Darn! This explains what's happening: the firmware configures pin PD6 as an output which means that the state of that pin is continuously overwritten by the blinking LED logic.
I was lucky though that Arakula has managed to reverse-engineer the controller. While I couldn't get a working build out of it yet, I actually could follow Arakula's comments to the point where the PD6 port was configured and patch Soarer's original firmware file. Attached at the end of this post you can find a patched HEX file for ATMEGA32U4 which no longer tries to blink the "onboard" LED. Use your favorite programming tool to write the HEX file to the controller, then download Soarer's Converter tools (linked at the top) to build a Soarer Config file (scas) after which you can send it to the controller with scwr.
And if other people building a GH60 or clone might be interested, here's my jbert_gh60.sc file (only Colemak-on-QWERTY mode is commented out, get it from Soarer's converter ZIP):

# Note: - FN3 is actually used for the 1U key to the right of a 1U backspace
# - FN2 is accessible to the left / right of RSHIFT if you use a narrow shift key
# - EUROPE_2 and BACKSLASH can be swapped for a UK keyboard but I've always liked the backslash close to ENTER
