The quick solder method will still work if you can reconnect the legs of the chip back on traces which they were originally suppose to be. The dremel was used to expose more of the legs so he can solder to it more easily.
My mistake saw the pics here

Read some posts on maxconsole forums.

Saw some pictures up at maxconsole forums where some person used a dremel to grind away at the chip to expose the legs and modded it that way. I suggest you only try that if you have major skills at soldering and the use of a dremel.
