Accept a position as "Lead Developer"?

There's a promotion on the table for me to take over a small IT department at a smaller company that has different needs than the parent company it spun off of. It's not a heavy management role: there'd just be one network guy working for me. I love coding more than just about anything... but this looks like it'd be more of an analysis and knowledge management thing. I'm probably going to take it because it's the only way "up" in my current situation... but will I have killed my chances for becoming a hard-core heads-down code-cutting developer in the process?
