If the discussion on the GPL Wikipedia page (http://en.wikipedia.org/wiki/GNU_General_Public_License ) is representative, you are not alone but nevertheless it is not clear-cut either. The debate revolves around the definition of "derived work" for software. If you fall into the camp that believes any call to a Linux-specific system call makes the calling program a derivative of Linux, then your example is clearly a violation. I think the majority view is that there are categories of linkage that remove the "derived work" designation even when the caller is useless without the callee. The GPLv3 implicitly acknowledges this as it addresses situations where the proprietary elements of a mixed system of proprietary and GPLed software impose constraints on substituting modified versions of the free software components (tivoization).

Short answer: the proprietary parts are asserted not to be "derived works". You are free to disagree, but only the judges' opinions count.
