I did some further investigation into this. I downloaded the alternate ISO and it stopped at the "Detect and mount CD-ROM" step. I flipped to Alt-F2 and ran dmesg, comparing it against the precise-server ISO from the same date.
The server build successfully loaded the ISO 9660 extensions, but the alternate build had no such line.
