I considered using a standard PC CPU for a custom EFI board, but have you 
looked at the Pentium datasheet? The mc68332 is a microcontroller CPU, so it 
is pretty stand alone, but with the Pentium there is a much needed chipset to 
manage the complexity of it's signals. Even with the stone aged 8088, Intel 
was recomending the use of a a chipset (8288) to arbitrate the bus. But al 
least this CPU has a stand alone mode (called MIN mode according to Intel's 
datasheet).
For me, the x86 CPUs are WAY out of my league for a homemade board.
