Thanks for the response Jerry.  I'm in the middle of trying a different 
approach, but I'm willing to do it the "right way" if there such a thing.

My use case is:

I have two identical servers, each with a single SATA 500G drive.  Each has 2 
NIC's being used as 1GB x-over, and 100MB for the network.
I plan to host virtual machines on a Debian Lenny OS with a large shared DRBD 
mirrored partition. (and hopefully linux-ha with bonded IP's)

I also want (but don't need) the disk fully encrypted, excepting the small 
boot partition.
---------------------
Currently, my new plan is this:
unencrypted sda1 /boot
encrypted sda2 /
unencrypted sda3 drbd-meta
unencrypted sda4 drbd-data
(and hopefully be able to use encryption on the drbd-resource)

TIA,
Colin.
