indeed, in-kernel entropy gathering can be made to gather entropy 
from e.g. active device drivers, using completion times etc., whereas
anything else must rely on executed userland commands and the like,
which must be horribly inefficient and lower quality entropy by

i would hope that this might come in an LKM which would be backward-
compatible with solaris 7 & 8 (at least), with an associated set of
modified device drivers (disk, net, etc) to feed the LKM... just my
thoughts.  (sounds like a big job, eh?  ;*)
