I am currently running SAVFL on my 10.04 machine. Support generally applies to AutoProtect, as we need to have a compatible kernel.
On 9.10 I was able to compile the AutoProtect kernel modules for my 64-bit machine, but I was unable to get it to activate. 32-bit 9.10 was fine. I haven't tried recompiling the AP kernel modules on my 10.04 64-bit machine yet.
