Juergen --

Thanks for the further clarification and especially for the simulation
results!

I think some things could be done to increase the cooling rate.  One --
as I saw mentioned elsewhere -- would be to use fat heavy traces and
pads off of all the pins. Another might be to remove some of the plastic
from the package. Third, a chimney over the chip could provide a laminar
flow cooling draft while at the same time reducing fluctuations due to
air turbulence. 

What so you think?
