Ah, looks like you were faster than I was with replying :-)

Did you check which formats offer srgb writing on Windows? Our pixel shader 
code offers it for all formats, although srgb correction is pretty pointless 
on float buffers

The geforce7/8 offer it on R5G6B5 and the *8R8G8B8 formats. Not sure about ati or intel but I think ati at least offers it on 32bit formats.
