I tried Cedega 4.2.1 and wow. It started quite well, but at certen occations the system hung (first time situation since I switched from Windblow$) At last it hung one time to much, resulting in a situation where all of my inodes were wiped, resulting in not finding any files on my disc.
I do have a better solution:
Cant be that hard to Find 20 000 gamers who wants to play World of Warcraft native under Linux?
Sign the petition now (takes around 50 sec to do, if you know your phone number and your name!)
TELL at least two friends to pass this action on!
(I got it running under Fedora Core 3 with Cedega 4.2.1, after my crash, I've hered that U should run 4.1 of Cedega when you run wow)
