I think, this is bad direction: if some external program unexpectedly
modifies nondeclared registers/parts (unimportant, syncronously (exoplicit
call) or asynchronously (hardware interrupt)), then should be fixed external
program, not added extra code into kernel. Especially, saving registers eats
prceious stack, whereas fd-emm386 _may_ be fixed without big efforts.
PS: We already seen similar stance, when there was trouble between WDOSX and
fd-emm386, which was modifies undeclared register (parts) accross its entry
point.
