This isn't precisely a pc on a chip (the core is MIPS-based), but Microchip's PIC32 offerings gives you a fully 32-bit processor with integrated RAM, ROM, and some peripherals for about $5 per unit. Perhaps not useful if you need x86, but plenty useful if you just want to compile and run ANSI-C applications (GCC has an appropriate MIPS target).
