I would stick with the vias - but here's how you do it. You'll need some things.
1) Magnifying glass.
2) A very sharp and small object - I use one of those dental tools a dentist would use to scrape plaque off your teeth. You know the thing, it has a little hook on the end of it and is very small and sharp.
3) Flux. I can't stress this enough. Don't even bother to install a modchip if you don't use a small amount of flux on your points. It makes the solder joints stick so much better.
First, you need to take that sharp tool and carefully scrape the via on one side of it. You're trying to remove the covering over the via exposing the copper of the point. Practice first on the outside of the board along the edges - you don't want a very deep scratch which might ruin it - just enough to expose the copper. You'll know you're there when you can shine a light on the point and have it reflect light back at you like a shiny new penny.
Next, use that same small instrument and dip it in the flux - you want a very, very small amount here - smaller than a pinhead. Put the flux right on the via hole.
Now, flux the end of your wire a bit then stick a very small amount of solder to it. The flux will help it stay on the wire. Now lay the wire in the small amount of flux on top of the via hole. Press down fairly hard with your solder iron and hold for like 1 or 2 seconds and you should be able to hear and see the flux burn off.
Now you should be done - I have no problem soldering to any size of point on the entire board using this method.
