Thanks everyone for the contributions.  I ran some test today with a real power supply and found the following:
* At 5.0V, with no LCD, the verdex draws ~300-500mA while idle, and up to 750mA while under load.  Old AC-DC wall brick was definitely not enough.
* At 5.0V with no LCD, the board seems to have some issues rebooting while using wireless (ssh or scp), but not wired for whatever reason.
* At 5.0V, with the LCD now attached and wifi module still connected, the kernel does not load all the way (it stops in different stages of loading each time)
* Upping to 6.0V, with LCD and wifi, the kernel loads fine, drawing 600-700mA idle and up to 950mA while using wired/wireless (wired actually seems to be more power-hungry for some reason).

So... is running the verdex at 6V against recommendations?  It seems much better than the alternative (no LCD)...

Cheers,
Felix

Yeah - the wifi module by itself can draw close to 500 mA when transmitting.
