[hpsdr] PS3 support in Linux 2.6 - Cool!

[Murray Lang]

What about development tools? I've been looking for information on the web 
but don't have a clear picture yet. Sony has released tools, but to who and 
for how much? Does YDL come with the GCC tool set? What's debugging like? 
Any DSP libraries?

I'd be great to have a discrete, quiet little box to do SDR. Are PS3s 
quiet? Also, I'd hope that EMI was no worse than a PC.
