Is there any reason why don't you just define I386_CPU instead
of modifying the header file ? This is done by the line
cpu I386_CPU
in the config file. Or has the full i386 support been already dropped
from the kernel by now (I remember such a discussion on
-developers) ? Hm, maybe we should add "VMWARE_CPU" then for
inclusion of any Vmware-related optimisations.
