I think in most cases you're better off testing the exposed DOM interfaces
of the filter primitives that you need, though that's not a 100% guarantee
either.
Here's one attempt, just paste this into each browser to see what it gives
back:
javascript:alert(!!document.createElementNS &&
/SVGFE/.test(toString.call(document.createElementNS('http://www.w3.org/2000/svg','feConvolveMatrix'))))
Cheers
