All 15 of our developer workstations; iMac 27", with Apple Cinema Display (MiniDisplayPort), and Dell 21" 2007FP Monitors in Portrait/Rotated (ioGear Adapter with DisplayLink 1.7 Driver) are having the same issue.

After upgrading to 10.7.3 (Combined), the machines booted to blue screens. Our solution was to boot into Safe Mode (power on while holding shift key), then uninstall the DisplayLink 1.7 Driver. Then, on reboot, the iMacs and the Apple Cinema Display started properly; without the Dell monitors. Afterwards, we reinstalled the DisplayLink 1.7 Driver, which reset the Dell monitors back to standard landscape mode.

Unfortunately, we need the portrait/rotated modes to work properly. So while we're now able to boot the machines properly, until the DisplayLink Driver is fixed to address rotation, we're leaving them turned off.
