Georg, trying first in a way and then in the other seems useless to me, just a delay. There's nothing that the legacy method can't render AFAIK. However, by the test I've done with a small app I wrote, dvipng is quite faster in effect, legacy requires from 15% to 75% more time, using LyX I didn't noticed it. Detecting packages unsupported by dvipng is not that simple, probably there are a lot of packages with this problem, moreover you can't just check just for PSTricks, but also all the pst-* packages, which include PSTricks. I'll try to ask on the preview-latex group to ask them if there's a way to quickly determine if dvipng will be able to render correctly the tex input or not. If nothing new comes out, I'll write a patch for lyxpreview2bitmap.py which detects TikZ and PSTricks and goes directly to the legacy mode.
