Installation Configuration - X screen test locks computer.

This problem has happened with 3 installation attempts.

SuSE 11.1 32-bit
HP Pavillion a200n
Unknown video card (on-board)

The first portion of the install completes successfully. After that, the system boots for the first configuration. X attempts to configure the video and displays a few test patterns. The computer becomes unresponsive on the second pattern. Unresponsive meaning a couple hours of displaying the same pattern.

What is this?

Thanks in advance.
