THOSE adapters only reroute some signals. they leave the vcore 
generation completely untouched and you can easily burn your board's 
regulators. that's why they are so cheap. additionally those adapters 
don't change voltage levels of some important signals esp. PWRGOOD. this 
signal needs a level of 2.0V according to intel's specs. on some boards 
it is just connected to vcore. with vcore way below 2.0V the cpu will 
never start, not even with this adapter.
everyone with medicore soldering skills could rework a S370 to achieve 
the same within 5 minutes.

but apart from all this: the bios (not even linuxbios) can distinguish 
between a fcpga/fcpga-ii board and a ppga only board. only if all boards 
were handtested by someone. this leads me back to my first thought: all 
slot1 and s370 boards get support for all slot1 and s370 cpus. the bios 
picks the correct handling routine during runtime like current bioses
