If you are refering to the code in arch/i386/kernel/setup.c, the code that
determines the features is spread over several hundred lines of code which
makes decisions based on model info and various erratta.
If an application included this directly into itself, then it wouldn't be able
to handle new CPU models, erratta, etc. By letting the kernel handle it, it
will always get the best possible info.
