It appears to be correct, it's just too fast, see below

I think it's the build in 114ms repeat rate that I find too fast,  
often being interpreted as two button presses. I tried using evtest  
both with the console, which yields additional keyrepeats after just  
100ms (i guess it's exactly 114ms), and under X11, where there's a  
delay of about 250ms before any additional keyrepeats. The repeat  
rate seems to be the same in both environments. However, it seems  
that after running X11, the delay is set to about 250ms also when  
running evtest in the console.

I found this article interesting: http://www.linuxjournal.com/ 
articles/lj/0107/6429/6429l12.html . It describes how one can set the  
repeat rate and delay using the EVIOCGREP ioctl. It would be  
interesting to get in a patch into the remote plugin to do this, but  
for now I'm just using the attached small program.
