Which architectures does BusyBox run on?
BusyBox in general will build on any architecture supported by gcc. Kernel module loading for 2.4 Linux kernels is currently limited to ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC, S390, SH3/4/5, Sparc, v850e, and x86_64 for 2.4.x kernels. With 2.6.x kernels, module loading support should work on all architectures.
