I've made some tests... interesting results averaging five pictures got with +1EV bracketing.
This is like an on-camera HDR function, isn't it?

It would be interesting to compare the two methods against one another...

that's what I did before posting. I took five pictures (+2, +1, 0, -1 and -2 EV) in RAW+JPG
I did the RAW Average in camera (A630) and got a new "averaged" RAW file.
Also, I did the HDR using PSC2 with the five jpg,s files.
I adjusted both final pictures at my taste... and got two photos not identical, but both of them had higher DR than normal pictures.
With a little of care that horrible (for me) "paint effect" you talked about, can be avoided.

Thanks indeed for your explanations

this may definitely turn out great but everything that is averaged with overexposed areas turns out pink in my cam.  :(
it would be great if a solution was found. in camera HDR... wow

make burst raw shot (4-8) at iso 80 without any bracketing, average it, and you'll get very good results...
at 8 raws you will get a very clear image and less noise
if you want to remove pattern noise turn on NR, it will help a little bit
and of course use tripod
