Module load order should never cause any change in operation. If that
happens, it's a bug.

Looks like the exclusion list is incorrect in hid.

The requestor would do good to attach /proc/bus/usb/devices so that
we have something concrete with which to go to Dmitry.

Upstream discussion:
 http://lkml.org/lkml/2006/9/30/181

After reading the upstream discussion I was wondering is there any resolution to
this in the kernel? 

> it can't be blacklisted by the existing quirk bits, can it?

Implies that it can't as there is currently no reply, I hope to see this supported. 

Yes, it turned out not to be a trivial patch as I hoped. So, someone has
to do the work, and I have other things on top of the pile.
I'm going to keep this bug open as a reminder.

Quoted from the mactel linux users mailing list. 

This may help.

Thanks Soeren. That did the trick. Not sure why I didn't think of it 
myself. I had to do something similar with alsa to get a card working a 
few years back.

I've never used the synaptics driver before, but if you lightly touch 
the pad and then move, it doesn't register. I'll assume that has 
something to do with one of the many settings in xorg.conf.... Time to 
poke around.

Thanks again Soeren. Much appreciated. I'm really liking the double-tap 
right click.

Are the any plans to patch appletouch with the new usbid's as per the mactel
patches?

Actually it looks like patch-2.6.20-rc6 contains that patch - so looks like it's
en-route .....

I have the same issue as the original reporter.
Running on a Macbook Pro Core Duo (first generation). I tried the latest kernel
with the included patch, but that doesn't seem to help.

So it looks like I should have a GEYSER_3

Possibly there's a way to do this. Appletouch contains code to set the device
mode of Geyser 3 and 4 devices to something other than USB HID. If this would be
done in inside the HID driver too, somewhere before it starts to take control
over those devices, this should give us what we want. The keyboard part could be
handled through the HID driver, whereas the touchpad would be ignored and
eventually picked up by appletouch.

It's just a thought. I can't try it myself, because I have no way to get my
hands on a MacBook.

Well, somebody has already done the work:

git commit: a417a21e10831bca695b4ba9c74f4ddf5a95ac06
Not included in 2.6.20, though.

It's seems to be in 2.6.21-rc1. I haven't been able to try it yet, since that kernel won't boot on my 
machine, but that's due to bug 229607.

I have the same problem as Ruben. The best solution so far is to backport patches

00081d3729a450c37afb01c01528f4f305806d86
009ad0e7b43d6cabd74e47db6180f14315b71417
e5d9A832c207f952e15ccddda5f2d52c94036acd7

and compile usbhid as a module. To get the two button scrolling to work one also
has to upgrade the X driver.

Karl, did you have a chance to try F-7? Does it work?

Fedora 7 works great, in fact I was meaning to come and close this bug.

:) Still waiting on two finger scroll, I can't figure out why the settings in
the man page don't work in X, although I've got edge scrolling working and
two/three finger tap.
