Has somebody a stable Ubuntu Studio NATTY 64-bit?

IMHO, if you can't go higher than 48KHz, then I'd actually stick with 44.1KHz throughout the entire production flow, assuming that's going to be your final sample rate.
Downsampling from 48K to 44K actually causes some artifacts in the higher registers. They occur in all downsampling algorithms, but they actually sound worse because the sample rates are so close together. Whatever audio quality you get from 48K vs. 44K is negligible, in my opinion, and won't offset the degradation from downsampling.
Of course, if you can go much higher (like 96K or 128K), then it's certainly worth it.
That's just my opinion, of course.
