Hmm. But int xx interfaces *still* need to be in 16-bit
assembly. Still, it might be nice to provide description "how to call
this from 32-bit prot mode", i.e. specification saying:

BIOS can be called iff CS contains selector with base = 0xf0000 ...

You *must* have int xx calls, which are 16bit, or dos will not boot.
