Note that Windows drivers disagree on which format they support. Nvidia has V16U16, AMD supports Q8W8V8U8, at least on r200. I am working on a more comprehensive converted format test that tests all supported signed formats with surfaces.
Just out of curiosity, do you happen to know if any hardware/driver supports these for render targets?

I think d3d10+ cards do. This is from memory, I'll boot some of my Windows machines to check.

My evergreen GPU supports Q8W8V8U8 and Q16W16V16U16. The two Nvidia GPUs I checked (650-something and 460-something) don't support any signed formats as render targets in d3d9. The refrast doesn't support them either.
