Comment 19 for bug 117773

The fast solution is described at https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/117773/comments/15. Just copy i2c_ec.ko of the .15 kernel-version over the new one. This will also work for future 'security' updates of the kernel as long as the respective ABI is stable, i.e. who knows how long.

The real problem is that the Ubuntu kernel team releases untested non-security patches as part of a security update. That is the work of amateurs (amateur is about the nicest word I can find for it ;-).
