Using the stack makes alot of since for the return value of the assembler 
function.  In the case of no parameter, I suspect you can just call the routine 
via a function pointer in C. Set that to the address of your assembler routine 
and call the function.  Please bear in mind I am not a Power C programmer, but 
am just guessing based on other platforms I program on.  If you have parameters 
there could be some documemtation on how to pass them via registers in the 
compiler docs.  Compilers seem to have their own style for stuff like that.  It 
also could be that you just need to drop the values into a certain memory 
location as the assember routine expects it there.

Not sure I follow you about the too few parameters.
