Not in the way I'm imagining it.  You want each *whole partition* on
the disk to be encrypted as stored on the disk, which means that you
need to decrypt it on-the-fly, which means that the decryption is done
in a Linux driver, not in the boot program.  Are you thinking of
decrypting the whole disk (into...RAM?!) and passing that to Linux?
You'd still need to enter a password, else store it in cleartext where
the boot program can get it.

Let us know what the product was, and maybe we can work from there.
