OK, but Dave did write "I seem to recall ...", so he's just pointing you in 
a direction, not giving you text to search for in the data sheet.  Look in 
Section 8, System Clock and Clock Options.  You will find that indeed the 
ATmega32(L/A) parts are shipped with the clock divided by 8, just as Dave 
said.

That's because there's no change here.  Maybe Dave wasn't suggesting that 
there's a change, but rather that there's more to bringing up an ATmega than 
loading the program.  Perhaps you should compare the fuse settings for the 
parts that work and the new parts, that don't.

I think that would be great.  I hate it when the OP does not post the 
outcome.
