Ok, this solved the problem with the temporary file. I should have tried
that by myself. ;)
The filesystems are still not mounted after reboot. This is, because I
preloaded the zfs.ko module. ZFS seems to try to load the cache, but
rc.initdiskless has not been run and therefore there is no zpool.cache file.
If I load the the module from a rc.d script, which needs to be run before
rc.d/zfs, it works as expected.
If the loader could preload files from a different partition
(ffs, w/o bsdlabel), it would be possibe to preload the module. My first
experiments however failed. But since it works the way I described above
this feature would be nice to have, but is not mandatory ;)

Thanks,
Oliver
