The rules ares changing for length of resume. In college, yes, it should just be one page, but that's because you most likely don't have any experience. The one page limit works because it makes you focus on the meat of who you are.
However, as you gain experience, then the one pager can become an artificial limiter. As many people have explained above, tailor it to the job you are applying to. But in the hacker community it will be important to show things you work on for fun as opposed to things you do to pay the bills.
My resume is currently 3 pages. First page is what I love to do (projects I am working on and consider important). Page two is how I get paid. Page three is education, skills, references.
I can tell you as a hirer I would most likely not seriously consider your resume. You might think that is unwise, but you clearly don't know what it's like to wade through a pile of crap from people who are obviously just spamming every job opening they can find, trying to find the few people who are actually reasonable candidates, before even trying to figure out which ones might be any good. Even using a recruiter is of limited use -- you can give them criteria, but they often just don't know to tell the difference between a real programmer and someone who has put "programmer" on a piece of paper.
Three pages, with skills on the third page, is roughly as rude as walking into my office and unplugging my computer.
