Unfortunately, usability is as much about practical use as anything else and so if green text on yellow increases readability but bores most users to leave the site it's bad usability:)
I wanted to try to submit some links to this site, but decided to pass on this one because of FOUR major problems with their study:
1) although the study excluded color-blind people from participating (???), they mislead people into thinking it's a great color scheme for the general population
2) they said the color combinations differ for common fonts besides Arial, so it's not a good rule of thumb
3) computer LCD monitors could very well make green text on a yellow background very hard to read even for people with normal vision
4) The effects of reading very long pieces of text were not tested
Reasons #1 or #3 alone means I would not use that color combination without further testing with color-blind people as well as on older LCD screens. (Note, the study is down at the moment so I can't double-check what I said.)
