Yes, I realize that now. What did you use as your starting point for compiling the kernel? The gem5 wiki download's page recommends the "Developers and Community Builds" section here http://www.linaro.org/downloads/. I wouldn't necessarily recommend trying the most recent ones, but there are kernels for Versatile Express. I'm not sure what changes need to be made (if any) to get them working in gem5. Example: http://releases.linaro.org/11.12/ubuntu/vexpress-a9/
