Comment 13 for bug 107774

You could keep the modified initrd just fine, the way I recommended you modify the initrd should keep across upgrades and such.

I experienced this bug with 2.6.20-4-386 and 2.6.20-4-generic, which means by 2.6.20-5-386 and 2.6.20-5-generic it should be fixed. However, I'm not an ubuntu kernel guy, just a regular kernel guy so I don't know what sort of distro policies they have in place for releasing important critical parts of a linux system. 2.6.20 in general was a much better release of the linux kernel than most of the other releases (imho), so any continued work on that version of the kernel should only get better.
