AFAIK the N800 uses some kind of special ALSA plugin for output, that
is not the most compatible example of an ALSA plugin. I am quite sure
Marc-Andre Lureau can tell you more about this.

Because QEMU does not support the ARMv6 opcoes yet binaries for N800
are built for ARMV5 in nmost cases. Also, note that PA/libatomic_ops
does not contain native support for either ARMv5, or ARMv6.

And also, the atomic ops should not have any influence on the sampling
rate ;-)
