V8 can run on ARMv4 devices (non T though). There is no interpreter in V8 so you will be using the JIT every time, perfromance should be good (keep in mind CPU like 926-ej-s do not have L2 cache and this is going to have a visible impact). There is a new JIT infrastructure being developed (crankshaft) which features an optimising JIT and this will only be for ARMv7+VFP devices.
