1) It doesn't matter how much KDE takes - the RAM is always written and read 
completely, not partly.
2) Those 800 MB definitely include a lot of apps running. What does top/free 
say immediately after you booted the machine and logged in (bootet from the 
state of being really switched off, that is)? Mine says about 240 MB (32 bit).

Compared to KDE3, KDE4 takes longer here, as well. But not that long. The 
laptop's screen goes off and on once or twice, which may account for most of 
the delay. And the mouse pointer doesn't follow the mouse for a second or two. 
I have never measured it, but I guess it takes around about 6±2 seconds from 
switching on to seeing the password screen. (Provided that I move the mouse 
right away to make KDE show the screen).
