No we don't. That was just a hack to keep the size of the patch down.
Something like the patch below (applies on top of my previous patch)
would take care of this, except that it renames the psmouse module to
psmouse2. To fix this I think we have to rename the psmouse.c file,
and I didn't want to do that in the original patch, because that would
have made it much harder to review the patch.
