Perhaps you could describe what actually happens?

I *think* it's about 2.5M, but I could be wrong.

Initially, the only memory space you need to worry about is that occupied by 
the kernel itself (restricted to 2.5M). Modules are loaded into a different 
area of memory which has no restriction (except for the amount of RAM 
naturally).

I don't know about 2.6.x kernels, but I normally find two versions of the 
kernel are created during compilation. One which is in the the root of your 
kernel source tree (I think this one is stripped) and one which is it 
./arch/sparc/boot/ (I think this one is unstripped and therefore larger).

I could be completely and utterly wrong, but that's how it think it is.

If you are mostly concerned with IPTables, then why not use a more stable 2.4 
kernel? I've had 2.4.21 running well on a SS20 SMP for a while.
