I'm a non-trad student and took the first semester of physics 12 years ago. It hasn't caused me any problems and no one has even brought it up in any interviews. I get the feeling that as long as you've done well in other science classes you've taken more recently it's not something most schools care about.
I would double check with every schools you're hoping to apply for. Some schools, like Arizona for example, are requiring that all prerequisites have been completed within 5 years of the date of application. Seems like your 2009 class will be fine for apply for this year, but maybe not if you need to reapply next year.
