There's probably a cleaner method of accomplishing this, but I've been unable to find such readily available.
First of all, a camera shot showing the absurdly pixel-dense display in all its Retina glory inside OS X:
MOD EDIT: BROKEN LINK
I used a trial of the software package SwitchResX.
Within the SwitchResX Control panel, choose 'Display Sets'.
Create a new set with your choice of name and keybinding with '2880x1800' in 'Millions of colors'.
Save, Apply (reboot if asked), and hit your global keybind to activate the new resolution.
Some things of note: The Quartz window server appears to freak out at this resolution on a cold boot at the login screen... you can still see what's on screen, but there is graphical corruption until you login.
Hopefully someone will disclose a cleaner solution sooner than later. In the meantime, this workaround does the job.
