$ uname -r
2.6.27-1-generic

$ dpkg -s linux-image-2.6.27-1-generic | grep Version
Version: 2.6.27-1.2

The same setup worked on a Hardy install with default everything, i.e. linux-image-2.6.24-19-generic, Version: 2.6.24-19.41

Not a bug. You must install/upgrade linux-restricted-modules-common to get the firmware.
