If it is supported, YES.
There are 2 drivers that work with USB to VGA dongles. One is the SISVGA driver, the other is the DisplayLink driver.
This provides a simple framebuffer device to the system that can drive a VGA monitor. You need to custom build your openwrt image to have it turned on though, and to enable the main system console to run on the virtual console hosted by the framebuffer device (And NOT on the physical serial port usually inside most routers.)
Here's a blog detailing the process for getting the displaylink driver working.
Putting a USB2 hub on the lonely USB2.0 port on the back, putting a keyboard, mouse, and USB2VGA dongle on, you can directly hack away on the router. Even without the keyboard and mouse, the framebuffer device can be used to display data about the current status of the router in real time, and other fun things.
