It may depend on the sort of jobs you're applying for, and there may be cultural differences. For the area I'm familiar with, high-tech non-defense jobs in the US, I'd say leave the old grades off. I've heard that in some other countries, there may be more emphasis on having followed the "correct" path.

I'm trying to remember if I've ever seen someone with an advanced degree put their bachelors GPA on their resume.

If someone asks about your bachelors grades (very unlikely), you've actually got a great story that proves your ability to achieve your goal (graduate from college) in the face of outrageous obstacles. I'd say that's a much more impressive achievement than most recent Masters graduates can point to in their undergraduate record!
