See the thread I > started about plugin modules the other day :) I think you're thinking of some other board. Cardhu is a tablet reference platform without pluggable modules, and I believe the PMIC mess is just due to some rework in later board revisions to solve some under-power issues in the earlier variants. But I believe there is some Tegra30 reference board equivalent to Whistler with all kinds of pluggable modules, although I haven't touched one yet, and don't recall its name.
