[Wine] Medal of Honor: Pacific Assault Problems

[vDub]

I've noticed a couple problems running Medal of Honor: Pacific Assault under Ubuntu 10.04 using Wine 1.1.44 and I was wondering if anyone knew how to fix them. 

1) The video is incredibly slow...it's similar to a fullscreen game running in a window (for lack of a better description), although I'm playing the game in fullscreen.

2) The mouse cursor remains present even after the game has launched and when I move it around, it acts like it's tethered to the center of the screen although when the in-game cursor appears, it acts normally.
