Well, I've changed 

gpm -m /dev/psaux -t ps2 -Rms3

to

gpm -m /dev/psaux -t autops2 -Rraw

And here comes the funniest part: either I set the protocol to 
"NetMousePS/2" or "IMPS/2", the wheel now works... ONLY FORWARDS !!
I mean, the scroll works as sliding down the scrollbar, not as 
sliding up.
After spending (investing?) the whole evening trying to hack this (and 
some audio issues and a little perl script), I consider my hacking day 
finished. Now it's time for a beer, perhaps tomorrow I'll have more 
luck.

Thanks everybody for your help !!
