none of it stays.  virtual memory needs to be off to let the booter put
code in memory (real memory) and then kick out MacOs

Only in that it probably takes longer to boot newer MacOs's so you have to
wait longer to get to NetBSD.  Actually I have observed that on my machine
I have to boot with extensions off with 7.0 to boot NetBSD, but can boot
with extensions and go into NetBSD with 7.5.3
