So i386 kernel does not create /dev/cpu/microcode as far as I know.
I do not know about x86_64 kernel, but file /usr/share/doc/kernel-doc-2.6.9/Documentation/Changes
describes /dev/cpu/microcode under title 'Intel IA32 microcode'.
Also, it says that if udev is not used, you might need to make mkdir, mknod and chmod for the device.
