This is more or less what we have for ARM 32-bits anyway. A nightly
check-all would already be of great help, though it'd be hard to count it
as "don't break" target with that turnaround.

With LNT you can run the whole simple tests or individual tests, so if you
need a more fine grained control over what gets tested, you can.

I'd think that time is more important than coverage at this stage, so if
you can set up a number of tests with enough coverage that would only take
a few hours, you could go for that. When you get a faster model, or an FPGA
materialises you increase the number of tests, and so on, up to the full
test-suite.

At least that would keep the "don't break" status because you could fix and
test quickly afterwards...
