Layer 3 always has ground separation from layer 1 in the intervening ground plane on layer 2 and likewise from layer 6 by layers 4 and 5. So I'm not worried about those signals.
ok great.
Regarding the SATA power: Is it an important part of providing a SATA interface? If so, I would suggest not limiting our options on this card. My understanding is that SATA is significantly more efficient for harddisk data interface than USB.
SATA was on a very preliminary version of EOMA68. it was cut a long time ago.
Regarding SD0: To what interface does it belong? What is the maximum data rate on this line?
MicroSD card reading (and other SD/MMC / SDIO compatible interfaces). i *think* it's a max datarate of 50mhz....
