They are rather expensive, so we decided to remove
them. But the power supply is now behaving a bit odd,
so in rev 3 some of the caps will be back:)
If you look closely you see a stack of caps just
behind the DC/DC converter. They were added
to add some more stability to the output voltage.

indeed - I was a bit shocked @ the price of poscaps. 13 of them are hiding on the underside of my DC/DC converter.
Calculating Rtune & Ctune via the GigaTLynx datasheet was vague to say the least
