CPU features set should be runtime options - could be done for most of the CPU stuff without emulation slowdown at all.

6. CPU 6. VGA
6.1 This was asked in the ml, and I believe it's a good idea to provide
a configure switch to set the cpu model, for example :
--with-cpu-386
--with-cpu-486dx
--with-cpu-pentium
--with-cpu-pentium-mmx
--with-cpu-k6-iii
--with-cpu-amd64
and so on. The main difficulty here is to set up the list of features
by cpu model. I started such a list, available at
http://cbothamy.free.fr/projects/bochs/CPU_Features.sxc
The configure script will then set up constants on features to compile in,
ISA, FPU, MMX, 3DNOW, SSE, etc... Most of the feature flags already
exists in config.h, so this should be easy. It would also be a good
idea to clean up the cpuid function beased on those flags.
We also have to keep in mind that some features are also enablable
by the guest os.
Please note the all features are still not supported/complete in Bochs.
6.2 Stanislav thinks that configure --with-cpu-pentium-mmx --enable-cpu-level-4
would create lots of conflicts in the generated config.h. He suggests
that we should write an external GUI configure script that would propose
standard or custom cpus and would detect conflicts.
