Thanks for the tip! And yeah, i'ts javascript/actionscript 
not much string to int / into to string stuff needed there
I am now getting readouts, however, it's hovering at around ~1023 which is the max for a 10 bit ADC, but i'm not moving the gyro...
What could this be?
I'm using this guide to get to the angular rotation speed (in degrees, ultimately).
[edit]: okay, wth, to be sure i'm now also measuring Y out 4x, not just the X out 4x, and they're both 1023 exact and not changing.
What can be the cause of this?
