one page, with major points extremely visible (larger, bold, etc). well-designed and easy on the eyes. and you should modify your resume to each specific job you apply for. why? two reasons (this is information i've obtained from HR personnel that i personally know, it isn't simply heresay): most resumes go through non-technical HR people. they aren't involved in the department doing the hiring -- they're just there to screen the resumes. if a resume _appears_ irrelevent, they will trash it. if they have to read it in full to effectively screen it, they will trash it. some HR reps will trash multi-page resumes just in principle. the point is, they will spend less than 30 seconds per resume and any obstacles to that time limit will get your resume screened out. second, you don't want to tell your whole story in novel form on your resume. your resume is your hook and you want to reel in employers to get you on the phone or in person. that is where you get to talk to them in detail about what you do, what you've done, and get to impress them.
