I would say you should look for companies where the software is the product and start applying there. When you are a support role in a company in which the product is something else you will always be an expense by definition. You can either jump ship or document precisely how you are making the company money. When it comes time for review give the reasons that you are worth $x more a year and back it up with actual numbers. For example, I had x idea that I implemented and by the metrics I put into the software I was able to measure a y decrease in time spent accomplishing task w. This led to a increase of profitability of $z and n hours saved overall.

I would say that jumping ship to a company whose focus is software would be more fun and bring a larger monetary increase. The economics of today is that you really can negotiate a larger salary by moving to another company than just getting marginal cost of living increase raises.
