Look here:

Here is at least two separate identical distributions of the Intel
"architecture", so it can be done and has happened.

Perhaps x86_64 will be fine-grained enough to define a pleasant platform
seen from an audio developers perspective? Which means death to sse,

IIRC the current celeron 540M should fit the definition for a low cost
alternative.
