This is all ignoring the fact that the spec has been published and 
available for a year. We've already had one report from Luke of a 
independent team building an IO board product that had to change their 
plans over an assumption of the non-EOMA-68 interfaces on the A10 card.

The simple fact that changing this revision of the EOMA-68 standard is 
not practical. There is a proviso that the standard will be revisited in 
2-3 years at which point we can re-eval the interface choices on the 
EOMA-68 interface for Version 2.

Also of note is that LVDS is on the EOMA-CF published spec.
