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).
