I spent some time yesterday on various Autocad trials, and so far i have managed to get Autocad 2004, 2006, and 2007 trial running. Someone else reported he had 2005 and 2008 running. I haven't had any lick with the 2008 LT trial yet though. For the installer to succeed you'd have to patch wine, so compile wine from source. I didn't do any deeply testing, so it might be that the various version still have various issues/bugs they run into.
