The 4K stack option is 2.4 specific. The issue is for all kernels. In the default and 2.4 mode you have about 6K of stack shared between interrupt handlers and kernel task context. The worst case for the IRQ handlers is reckoned to be about 2K so you have about 4K left for apps. The 4K stack option provides seperate IRQ stacks and while it doesn't change the safe amount of stack to use it does mean that programs that use too much stack that generally worked before now go boom.
