On our low-end HDS array (9520V), turning on "Synchronize Cache Invalid Mode"
did the trick for ZFS purposes (Solaris-10U3). They've since added a Solaris
kernel tunable in /etc/system:
set zfs:zfs_nocacheflush = 1
This has the unfortunate side-effect of disabling it on all disks
for the whole system, though.
ZFS is getting more mature all the time....
