There is absolutely no need for you to turn that into a matrix and test every combination. Do you work on 480x854 screens? Great, you have that covered regardless of the platform. And if you support 480x854, you must have already tested 854x480, since any device can be switched between landscape and portrait.
And in fact listing the different screen resolutions like that also makes things a lot more complicated than needed. If you want to work on the bulk of current devices, here is what you want to test: (1) Platform versions: 1.5, 1.6, 2.x (pretty soon just 2.1; 2.0 and 2.0.1 are on the way out). Most important are the lowest and highest versions to be supported; intermediate ones can be given a cursory sanity check. (2) Screen densities: test on a medium (HVGA) and high (WVGA) density to make sure you are handling them correctly. Throw in QVGA if you want to support small screen / low density devices. (3) Screen sizes: make sure your app works on the smallest and larger screen sizes you want to support. For example if you want to cover all current devices, 240x320 low density and 480x854 high density will cover it. So you should be able to fairly easily get away with testing: 1.5 HVGA, 2.1 HVGA, 2.1 480x854, and add 1.6 QVGA if you want to support small screens. Spot check other variations as desired (and knowing what your app does that it might get into trouble with).
