Can AMD/ATI GPUs be programmed in -- not sure this CPU terminology is appropriate -- assembly language?  Is there an instruction set  specification for the various cards available somewhere?  --Haven't found such things (yet) on an AMD site.

OpenCL is as low-level as you are going to get.

Since my OP I've found what I was looking for on the AMD site.  I also looked at the source code for cgminer and its assembly language module.

Thanks.  I also found this -- R600-R700-Evergreen_Assembly_Language_Format.pdf.
