There is an extension for floating point textures. It seems like ATI cards support 16 Bit and 32 Bit floating point textures. The extension states no limitation to 2D or 1D textures, so 3D textures should also be possible. However, it seems like there is no support for 24 Bit textures. Look at this page to see which ATI cards support this extension (the 9800 pro, for example, does).

I don't know if it helps but...

Nvidia cards don't support >8 bit floating point 3d textures. To get 16 or 32 bit floating point textures you must use GL_TEXTURE_RECTANGLE_NV, which is only 2D.

Maybe ATI has some similar restrictions.
