You don't need to. Paging is good, but not necessary. (gcc does, however, require a flat address space with 32-bit pointers.)

You can do it in the kernel. My paging setup code is part of the assembly-language startup code in the kernel and is run before any of the C code. It sets up a basic page directory with two page tables: one for the bottom 4MB (because the paging setup code itself is there) and one for C000_0000..C040_0000 (because the kernel is there).
