Hello!

Pretty much immediately after the beastie prompt, I experience some odd
scrolling behavior: http://files.kyle-evans.net/vt_scrolling.mp4 (12.5 MB)

I've experienced this with 11.0-RC1 install media, as well as setting
kern.vty=vt on a working 10.3-RELEASE system.

Machine is a Dell Optiplex 160 w/ an Intel Atom 330. pciconf output:
