Also met this issue in both ubuntu-14.04.1-server-amd64.iso and ubuntu-14.04-server-amd64.iso with USB stick to install. With the workaround from Chris Ball could bypass the issue, but the installor just hanged in another point as attached photo.
Finally got it work with ubuntu-14.04-desktop-amd64.iso and used tasksel to remove desktop parts.
The machine details:
# LENOVO ThinkPad W510 (43195RU)
# Intel(R) Core(TM) i5 CPU M 520
# Memory 4+4 GB
