The post install boot configuration screen does not fit on a 640x480 display.
Should be fixed in 1.0.0-1. QA, please verify that the screen resizes correctly now. If a resolution < 800x600 is detected, firstboot kicks out most of the banner graphics and so forth. The result is a little less visually pleasing, but it all seems to fit.
Fix confirmed with firstboot-1.0.0-1. Works for both 640x480 and 1600x1200.
