3 mouse emulation with 2.2.17pre9-ben1 + XF4

After installing the new XF4 on the 2.2.17pre9 kernel from benjamin, I lost my middle and right button emulation on my pismo.
I read for several days the thread concerning 3 mouse button emulation with the new usb stack (Franz Sirl),
but I wasn't able to make progress for my own configuration. I used before Xpmav.rev10.
Could someone give me some help?
(didn't find any info about it on linuxppc user either)
