Before you dive off the deep end, do the following:

[1] boot into run level 3 - no X, login as root and run the following 
commands, "free > f1", "ps -ef > f2", and "lsmod > f3". Post the 
results (f1, f2, f3) here. Maybe we'll have something to discuss.

On my box, free shows that the kernel + all the apps I'm running take 
12MB; a long way from 110MB. Of course after starting X and KDE things 
go downhill rapidly <grin>.
