Oh, ok, I think. The only kernel configuration option is to tell
it what memory "range" you have. The choices are 1GB, 4GB & 64GB.
The sid 2.6.12 binary kernel has it set for 1GB. So, if I were to
add more RAM to my current 1GB, I'd have to build a custom kernel.
As for telling the kernel what to swap, AFAIK, there are no build
or boot parameters to control that. Linux knows how much RAM &
swapspace you have, and does what it thinks is best.
