DT support for vexp A9 is going into 3.4 I believe. Pawel has been working on it and can probably give details on A15 support. A single kernel for these 2 platforms (and A7 as well) is much simpler than getting to a single zImage in general (i.e. omap plus i.mx). But we'll be a lot closer in 3.4.
Linaro's Android release for VExpress as be using Pawel's device tree patches for several months to provide a single image which works on A9, A15 and A5 CoreTiles. We haven't do this yet for Ubuntu because hardware pack and media create tools don't yet support this.
