   So I guess this answers a question I had -- apparently Apple doesn't 
have an internal (more comprehensive) Altivec test suite.  Does 
Motorola or IBM have a test suite that could be used or would a 
volunteer need to build one?

   It seems reasonable to expect a minimal test suite to at least:

- Call every PIM-specified function at least once, checking the output
	- Pseudo things like vec_splat
	- 'Real' instructions like vec_vspltisw
- Test error reporting for inputs (non-const arguments)
