I think 800dpi sould be safe, but you can test yourself if you have negative accel or not. Aim at some corner, with your mouse on the edge of your mousepad, move away really fast then go back slowly. If you are aiming at the same corner as before then you have no accel.
Actually you are in danger to have negative acc because of your high dpi(assuming that your windows sens is at 6/11 aka the mouse input is 1:1).

Btw Hog: In my tutorial there is this http://phoon.us/mouse/ link, but nowdays the site is down permanently, here is correct link: http://www.funender.com/quake/mouse/index.html
I'm gonna edit it to tutorial soon.
