Thanks Mojca for your answer and suggestion. There surely is something with my typescripts that makes them happy under mkii and very unhappy under mkiv. Switching them out of the way at least brings typesetting in LM back. 

However, I am attached to my use of Lucida and Mathtimes (both from Y&Y) and I would very much like to continue using them. Do you have a pointer with what to start? Would you give changing texnansi for 8r a good chance, for a first try? Or is more heavy surgery on my typefiles needed? I was never very good with typefiles and I fear very much I can start over all again for mkiv. 

For the regular postscript fonts like NewCenturySchoolbook etc. I will we be happy to use the TeX Gyre files for these. I guess they are already somewhere in my system. Would you please point me to a relevant starting point for the necessary incantations? For some dark reason I always seem to get lost when searching the ContextWiki for a specific topic.

Yes, it's quite possible. I don't have the fonts to test, but a few
possible relevant remarks:

1.) Try not to use that typescript and check if it still breaks

2.) Even if your typescripts are broken, there must be a bug
somewhere: luatex should not hang even if you feed it with junk; even
if you fix the typescripts, try to find the reason for that behaviour

3.) You use Lucida math; I would be surprised if it still works (I
would bet it doesn't, but I might be wrong.)

4.) It seems that the run breaks in type-psc (not 100% sure)

5.) [encoding=8r] ??? That's not even supposed to work in MKIV (unless
I'm wrong). Usually it gets ignored (and luatex just reads afm and pfb
files), but I'm not sure how exactly tfm reading works (if it works at
all inside typescripts).

6.) If you don't like TeX Gyre and think that using the old PostScript
fonts are still needed, it might make sense to revise your typescript
and make an optional officially unsupported (but public) typescript
that others could use as well (not sure if that would mean including
it in core or not).
