Yeah I heard bout the Win2k bit...but it isn't ready as of Win4Lin v4. And yes you'll need a Win9x CD and a valid serial of course. I doubt it has to be the official boot one tho. I believe just having the cabfiles on the CD would suffice. The whole thing is pretty fast though. I finished installing Win4Lin along with Win98 within half an hour. And the cool thing's that your virtual box boots up in less than 30 secs compared to Win9x booting up in minutes natively. Did you manage to run Poser good in WineX? I ran Poser4 in WineHQ's latest distrib of Wine a week ago and it ran miserably.
