I'll pay 1BTC if someone with a good rep can help me out here.
for my original attempt to just sell the prepaid $25 visa)
1) I supply Wells Fargo Visa Card details ($25 value)
2) You register the card on wellsfargo website to your valid US street address.
3) Use card via google checkout and mrcoins.org to buy 9BTC (assuming price doesn't change to much in the next little while - only just enough to get 9BTC at the moment!)
Send me 8BTC - Keep 1. (assuming you can redeem the resulting mtgox codes yourself - otherwise - send me mtgox codes and I send you 1BTC)
My mistake was to buy the card thinking that it could be used with US merchants - I didn't realize that the card had to be registered to the holder of a US street address. (I'm assuming google checkout will cross-reference this against IP etc?.. not sure but don't want to try it myself from here in Australia)
