OK, I've just had a look at it. There are many formats in the list, but most of them are not available as "render target" and even less are available as "alpha blend render target". It seems though that the hardware could support some floating point RGBA targets and some high precision RGB targets (using e.g. RGBA16 as render target without alpha blending effectively giving us RGB16).
