i donĀ“t think anyone can help you there. everyone here is using snow leopard (10.6.x), the netbookinstaller works just fine with snow leopard, not necessarily with Leopard. Since your 10v isnĀ“t a mac and the netbookinstaller specifically written to get working specific versions of snow leopard, iĀ“d recommend you to just kick leopard and get snow leopard... should be the easiest to get everything working.
If you want to be sure, install snow 10.6.0 (the first version without updates), install netbookinstaller 0.8.3, the update to 10.6.2. ThatĀ“s the best configuration i ever had with OSX on my mini
