Nah, you were right the first time :) Your system is defaulting to
160MB for the kmem_map, of which zfs will (by default) try to use up
to 3/4.  Naturally this doesn't leave much for the rest of the kernel
(40MB), so you'll easily run the kernel out of memory.

For now, you probably want to increase vm.kmem_size a bit to allow
some more room for zfs, and set vfs.zfs.arc_max and arc_min to
something more reasonable like 64*1024*1024+1 (the +1 is needed
because zfs currently requires "greater than 64MB" for the arc).
