Thank you very much.
This thread has been very enlightening.
Here's the end of story.
Adding the SR ring indication, make the symbolic matrix solving
possible.
Downside it's severa.l orders of magnitude slower than naive solve()
While tookme half minute doing the 7000 8x8 systems with pure
numerics...
it's been more than a minute and it hadn't finished 10 systems
Original solve() did about 200 systems per minute
So I'll jsut go back to the start point (althought with a much better
understanding of SAGE)
