... [snip] [General idea is to remove the option to save 16kB of kernel size] [snip]
Why not hand code all your C programs in assembler, you could probably also save 16kB by doing this. bash would be a very good target. This might take you long enough to not reply about how to save 16kB of memory. Even better why don't you become the person to add the patch for Linux to use spare video ram or the buffers on the network card for that extra few kB's of space. More seriously if _you_ want a kernel 16kB smaller with no random number generator, then _you_ remove the code and make it always return 0, or some other almost as useless random number algorithm (A shift register with feedback taps is probably one of the simplest decent pseudo number grnerators around).
Quite seriously, I know people have proposed using the Video ram as memory before, this RAM may have very good access times, especially if you optimised the memcpy & memset routines to use on card blitter chips. Also some computers have a few megabytes of this memory. Wouldn't be fun to debug though, especially if you try to co-operate with X & svgalib.
Thanks.
