Yeah, the lack of persistence is sort of a "feature" in this case.  If
you use the similar menus on most real hardware, they don't persist (you
have to go into the bios setup screens to make it persist).  That said,
if things were to persist, then we'd probably want to change the patch
to set something else which was looked at prior to the CMOS
