E1705 and Windows 7

I have seen some posts about Windows 7 and the E1705 and I'm wondering if anyone can give me the latest update as to whether I can go for it.

I list exactly what I have below (although I upgraded the RAM to 4gb and it uses something like 3.2 GB, and I am now on Windows Vista Ultimate).  I think I'm skepticle that this laptop can't make it to Win 7 because they told me I couldn't get more RAM to work when all I had to do was buy it and it worked perfect.  That really got me mad because I had it for a long time without more RAM even though I could do it.  So forgive me if I don't trust blanket "can't be done statements."  I like to know why and challenge assumptions until I know for sure.

I'm an IT guy so I'm comfortable doing some heavy lifting to get Windows 7 to work; and I've already purchased Win 7 Pro.  So despite Dell not listing this PC as Windows 7 compatible, can it be done?  If not, what is the detailed technicle reason?    Can I go to part manufactures websites and get drivers there if DELL doesn't provide them?

Thanks,

Keith
