The game runs perfectly, there are no slowdowns.
LINUX: You need to use WINE.
Just leave the settings at default (800x600 and High End preset on the options menu).
How much I played
Played the game on Linux, the first Saga (of The Empire) on Hard and finished it.
No issues found.
SHOULD YOU PLAY IT ON A NETBOOK?
You'll be lying to yourself saying: "One... More... Turn...".
