It took me less then 8 hours to make my first port, and I'm not even a C 
programmer, mine was a best case senario as there was a sibling board 
already ported. I have also ported some where just the component where 
supported, that didn't take to long either, probably 7-10 hours.

Working on a board where only legacy code and docs are available I have 
probably spend around 12 hours to get to ram init.

I think the key to sussess is to have an easy way to reflash the bios 
when your image failes.
