DIGITS looks like a serious attempt, but they don’t have too much of an incentive to have people developing for older hardware. I wouldn’t expect them to supor it for more than five years. At least the underlying Ubuntu will last more than that and provide a viable work environment far beyond the time it gets really boring.

If only they could get their changes upstreamed to Ubuntu (and possible kernel mods upstreamed), then we wouldn't have to worry about it.

Getting their kernel mods upstreamed is very unlikely, but they might provide just enough you can build a new kernel with the same major version number.
