Maybe you could ask for a hardware implementation of mul64by64_high...

Actually yes. The "pic mute" feature was disabled on AT91 because it was
causing latency peaks, but I plan to enable it ultimately. I think the
latency peaks were due to the fact that I was testing a 2.4 with the bug
which we fixed in 2.4.9.1, I just need to check that. And if pic mute
works on AT91, then I would implement it for other SOCs. And an upgrade
to 2.6.31 would be fine too.
