me too - i used wron search pattern, sry

looking deeper i found the method evals this: convertArgumentValue in 
ViewHelperNode.php

So i think you only can check

<f:if condition="{product.abc}">
for 0 (false) and any other value.

The if / else if with eval expressins like a == b seems not implemented.
