I'd suggest we do give all three warnings (KVA_PAGES, kmem_size, i386)
at once, preferably both when the ZFS module loads and when a zpool is
created. I think it's important that the tree pieces of information be
given at the same time so the user doesn't need to hunt solutions
after panics.

Your comment that people are panicking more than ZFS is correct, but
that illustrates the importance people give to having file system not
crash on them :)
