These aren't stupid questions. There are plenty of non-obvious things here.

Legacy mode SATA is where the SATA adapter responds to ATA commands.
Nvidia's ck804 (on the s2892) doesn't support that.
Because of that, you need something with a SATA driver to load your kernel.
1. port a driver to FILO
2. Use LAB (linux kernel with the driver in your ROM)

Are you going to use the onboard video controller? Did you include the VGA
BIOS for it?

Including the boot log once you decide which payload you want to use would
help us track it down.
