I think it's the best to keep it as simple as possible. If necessary, try to use APIC. But in your case, with the need of many simple machines, I would try to contact some mainboard vendors and get some information which machines would work without that APIC workaround. Once found a working one buy those and everything should be fine! By the way, I would try to flash the most recently bios for your machine. Maybe this fixes the issue that xenomai doesn't care about assigned IRQs in the bios (because this may be a bios bug).
