In that case, they might not have put posts or whatever they use to press them into the board for the usb hosts. If that's the case, we're screwed. We'd have to remove the proc and add a way to get to those pins AND be able to put it back in place.
From the pictures I see, I don't see much solder on those chips... not only that but it looks like a dual-layer board. Which means we'll never see those pins unless we buy a broken x51v and find a way to seperate those boards. If they eppoxy'd them together (as we do at my work) then there's no way to get them apart without destroying most of it. I bet you'd pull the traces right off the board. Even after all that work we may find out that there are pins there, but no traces. To get to the pins you'd have to seperate the boards. If you seperate the boards you're going to mess something up and you broke your axim. We really... really... really... need a board schematic... If Afarre still has his open, I'd like as close and as many shots of the sides of the board (to see if they are two boards glued together or if it is just one board) and if it would be possible to remove the label under the battery to see the board under it. If it's like... superglued on there I don't want you to break anything, it's just... well it looks like most of the processor stuff is under that label...
Also Afarre, on the part of the label you whited-out, do you have hardware version A00 or A01?
Right now I'm seeing my only option is the ratoc card... at least I could use a HDD and a touchscreen at the same time.

BGA format chips are soldered with a special machine like this:

The important thing is once soldered it is imposible to access IC pins.
The only ways to see if USB host pins are wired at motherboard and to find out were they go are:
- Getting information from Dell
- Unsoldering CPU. Does anyone have the machine? :exc: :exc:
- Having a broken motherboard to safely experience with it :approve:
And remember the final result could be: pins are not wired at motherboard, they are dead below the chip. In this case there is nothing to do.
