>Environment:
i386
>Description:
I tried to compile an i386 kernel that assigns reasonable device names (starting at the same number) regardless of the bus on which the device is found.

Unfortunately, npx* at pnpbios? results in npx1 when npx0 at isa? is configured in the configuration file.

npx* at isa? works when other bus is used for npx at runtime but causes infinite npxs to be configured when npx is accessed through isa at runtime.

I did not try with the other isa devices (fdc, lpt, com, pckbd, ...)
>How-To-Repeat:
add

change the line in generic kernel config to say 

npx* at isa?

instead of 

npx0 at isa?

 Fix: the FPU state should live with the cpu device.
 Consider the absurdity of a dual-core system with npx0 and no npx1.
