Well I am looking into building laptops as a way of making a living an the GFX card issue is a tough one, I agree with luke that you can't do it normaly an if you can its not a job for the faint of heart.
Jayce I am still googleing around for you nothing yet, I happen to sell that laptop at work an we got one returned this week so I will take a look myself at it if i don't find anything.
