265efa8b8b removed the "protect 386 registers" patch again, a fixed version of free- 
EMM386 is available. This reduces device driver call overhead in terms of
CPU and stack usage.  Older EMM386 versions destroyed eax ebx ecx edi esi
ebp fs gs, now go_driver_entry in emm386.asm saves those registers. Only
the INIT was broken, but the execrh.asm patch protected ALL functions.
