I removed most of my patches to mac_keyb.c before submitting them, I was
pretty sure I didn't break anything, but I was probably wrong. I'll have
a look at it as soon as I manage to get this vger tree (today probably)
and submit a new patch.

Here, I have rewritten most of the buttons handling in console and
buttons emulation, but my new version is not ready and was not included
in the patches I sent to Cort. I just checked my patches, and they should
not change anything to buttons emulation. I'll test all this later today.
Thanks for pointing this out.

Ah yes, could you send me a dmesg log ? I would like to soo how your
mouse was recognized at startup.
