Because they on the whole don't need any. The ones that do are DOSemu ELKS
and wine. Those use vm86 and modify_ldt which are in the kernel. Generally
speaking emulators don't need kernel help. Only those that use processor
resources and modes.

I think its almost an insult to think we are that crazy. Most of the ELKS
work is debugged under DOSemu.
