 Static? That comes as a surprise (busybox and the whole X-stuff are 
the only binaries which I didn't run through ldd). I'll play around with 
dynamic and static versions anyway just to see how the memory footprint 
looks like under different conditions.

 Are you avoiding ulibc so you can use Slackware-packages? ulibc should 
use even less memory. Or does it miss some critical features?

 About the kernel, have you ever looked into the more esoteric options 
for embedded devices? There are incredibly many options about stuff like 
filesystem-elevator and scheduler which could safe some bits here and 
some cycles there but all in all I doubt it is worth looking into it. 
Most embedded stuff is pretty ugly in pre-2.6 anyway.
