Oh, we've lots of that...

You can compile a kernel with M3 specific stuff - like 3DNOW support
(speeds up memcpy, stuff like that). Compile all your apps as if it's a
pentium, and you are away.

Not really. Consider it a Pentium with 3DNOW or whatever.

It seems to be about 20% slower than a celeron of the same clock speed.
The FPU is about 40% slower, at a guess. But, we've boxes with M3's in
them, running at 18 watts, so for low power/no fan stuff, they rock. But
in a desktop...I'm not sure. They cash saving isn't that great.
