Cell support is very very nice.

What I don't like is:

Older athlon processors (Thunderbird, duron) don't support SSE, they only 
support 3dnow.
And there are still a lot of these around. ( I only upgraded from one of these 
a few moths ago)

So for older non-SSE athlons, we need to support the current FFTW release.
For Cell support we need to support the next fftw release.

But I don't think it is nice to support multiple versions, especially if you 
want to use the new features of the later release.

I sent a mail to the FFTW guys about this, I hope they reconsider and just keep 
in the 3dnow code.

Greetings,
Martin
