I am running my Compac on the R1 using the standard U3 cgminer. It's kind of neat as it stands alone & I have pointed the R1 chip to Donate. R1 is running at 300MHz and the Compac at 375MHz.
aarons6 has ported cgminer-gekko to the R1 but I have not been able to get it to run at the moment.
Oh, well that's cool that it will work like that. Do you have the compac plugged into a hub, then the R1 (like it says to do for the U3)?
Also, how do you change the compac frequency while it's controlled by the R1? The pull-down menu is populated with frequencies for the U3.
It's a bit of a lash up at the Moment. I took my R1 apart & mounted it on a board with a fan and fan controller, plugged up an external 5V PSU to see how high I could clock it. Then when I got the Compac, that is plugged from the R1 USB via a Hub with a separate supply cooled by the same fan as the R1 innards.

I will tidy it up at some point, repackage the R1 and run it all on a single 5V supply and get rid of the Hub, but this is easier for playing...
The R1 runs 2 instances of cgminer with the familiar Antminer GUI and with crazyguy's firmware and a number of mods I have done adding frequencies and putting back the other stuff Bitmain took out in the R1 it works quite well.
