Macbook 5.1: Touchpad is not working properly after upgrade to jaunty

[acron]

Hi there,

after upgrading to jaunty may MacBook suffers from the bug described here.
https://bugs.launchpad.net/linux/+bug/337935

The short story is that usbhid is loaded before bcm5974 and grabs the touchpad instead of bcm5974 which should control the touchpad.
Removing usbhid and bcm5974 and inserting first bcm5974 and then usbhid fixes the issue.

Still the supposed walkaround to blacklist usbhid by adding
blacklist usbhid
to /etc/modprobe.d/blacklist.conf
and adding the following
bcm5974
usbhid
to /etc/modules does not work for me.
What can be the problem here? Any hints how I could debug this issue?

IDK how to fix the issue (yet) but please post to that report and let them know that it is still an issue in the final version of jaunty.

I could fix the issue be running:

sudo depmod -ae
sudo update-initramfs -u

as described here:

Thanks for your answer cyberdork.

I can do this no problem, but why would they assume the issue has been fixed? No patch or anything has changed the situation 'til now.

Edit: I commented the bug with the information above...

The problem was identified, there doesn't have to be a patch posted for a dev to fix the problem before release. This just confirms the bug against the final jaunty... not just a bug in the alpha/beta/RC. Thanks for your help.
