First of all thank all of you developers for the great great work!
I bit the bullet few days ago and installed WM2005
it's so fantastic!
But I realized that the battery life hasn't been imporved or it might have been reduced
So it got me thinking, is it possible to not have the RAMdisk and PagePool so that we don't touch the RAM at all and improve the battery life?
because one of the biggest improvment WM2005 brought was increased battery life by not keeping the votile RAM alive which consumes almost 50% of the battery life...
Just a thought...

ok... no reply
I must have asked a stupid question
I willl answer my self with self-made explanation.
Himalaya's hardware was designed to keep the SDRAM voltile at all time
so no metter what you do with the software there is no way to force
128Mb of SDRAM to asleep.
Damn.

i'm pretty sure that it's not the rom that deside if ram is kept powered when the device is off it's the device itself which handle that
so only nativ 2005 hardware would safe power
even unused ram would be powered because the hardware dont try to deside if random bits are random or your data
p.s. come to think of it i dont even think nativ 2005 devices turn off the ram when off because that would mean that applications would die when you turn the device off unless the system would place those applications which are suspented when off's memory to disk so their heap and stack info would not be gon when they started again when the user turned on the device
but some applications run even when off like notification and phone controlling applications so their would still need powered memory for their heap and stack
