OK, I must confess I was expecting something simpler :)

The level shifter (adg3304) is done and commited, please review.

Regarding the other components:

 * U7801 (WLAN module) - I could not find a proper datasheet for it [1]. We can derive information from openmoko schematics, but I'd really like to crosscheck
this with a real datasheet.

 * U7802 (Bandpass filter) - Our filter is not listed on their site [2], and datasheet access requires some access code.

 * CON7801 - Do we have this connector already [4] ?

 * ANT7801 - There was some previous discussion about this one [3], I am not sure if the symbol is ready.

 * Drilling and Shielding pads. Any ideas on these ?
