i'll give this a try and see if it makes any difference. i think 
you're right about it being a RAM problem, as the behaviour doesn't 
change if i start the machine with both U2 & U3 removed. i've checked 
the power/signal flow from the battery through the RAM to the CPU 
with a multimeter and this all appears to be working fine..checked 
the orientation of all ic's..
the 3.72 version of the firmware does give different behaviour 
though; when i boot the p3 after uploading by pressing F1 i get the 
LED-cycle and firmware&copyright bit, after which the first line of 
the display reads " tempo=80", 2nd line is the same as before. after 
a minute or so it jumps to the same kind of gibberish as before. 
also, i've yet to see the memory layout screen, in either firmware 
version. i think i saw a part of it during the boot sequence after 
uploading the firmware again, (it read something 
like "memLhard&soft") but never complete.

cool. i'll be waiting..
o and thanks for the quick replies!
