Go down to your local hardware store (take to Cyberstorm with you) and go to the loose nuts, bolts and spacers bin. Find set [color=FF0000]nylon[/color] bolts and spacers. Get varing thicknesses of spacers so you can build a standoff pin to with-in 1mm or 2mm from the board when it is seated. Then you can "bolt" the card into place. I'll post a couple pictures up after I get home from work. Only the holes near the card connector need to be done like this and the holes at the back of the card can use the standard standoff pins.
For me this was more preventative than to fix and actual problem. I just didn't like the supplied standoff pegs. They seemed to be to long and trying to push the board out of the slot.
