Ok, every machine in the cluster has a little cronjob that runs
a program/script every day. That script will ask to another
machine if it is its turn to make the system checks. If so,
the script will modify the booting options on the local
machine in order to load a ramdisk as a filesystem. On that
filesystem we will have the right tools for the testing and
the init scripts will end up loading a program which will
run all the tests to finally report to another machine the
results. After doing that, we can rewrite the booting options on
that machine and the machine would boot with the "normal" OS.
There is still one little problem: How do we run memtest?

This would be a nice way to take advantage of CARP.
