I mean that when a piece of kernel code is loaded, it stays in memory
unless it's a loadable module that subsequently gets unloaded.

Nope, you're not....

Perhaps the speaker *meant* to say that they could be *unloaded*....

SunOS 4.x doesn't, as I remember, officially support loadable SCSA
target drivers.  5.x, I think, does.  *That* may be what the apparently
rather confused speaker was trying to say....

Nope; you were, it seems, the only non-confused person in a room of 150
extremely confused people.  4.x's kernel is *not* pageable, and anybody
who claims it is simply doesn't know what they're talking about.
