I know about that. Actually, I wrote the current generic

Hi, LinBox uses the BLAS for dense matrices mod p where p <= 2^23, hence it
would benefit from advances in that direction. There is also some
(experimental?) code for dealing with non-prime fields in LinBox.
Furthermore, there is some code - AFAIK not in LinBox yet - for packing
multiple primes int
Tom, Simon's MeatAxe fork implements its own Strassen. But perhaps Sage's
asymptotically fast Gaussian elimination could be useful?

I might get blamed for making discouraging remarks, but let me play the
devil's advocate:
I wonder if these kinds of speed-ups are to be beaten, soon, by
sufficiently fast hardware implementations of level 2 and 3 BLAS, coupled
with some crude use of their super-fast vector arithmetic.

I guess making it standard would require to (1) make it an optional
package first, and (2) have a vote on sage-devel.
