Bugzilla 12483:

Kernel build fails with gcc3 (not gcc4), because
MODULE_DEVICE_TABLE(dmi, ...) expands to extern const struct
dmi_device_id __mod_dmi_device_table, and struct dmi_device_id doesn't
exist.

Steps to reproduce:
Build kernel 2.6.28 or 2.6.29-rc2 on x86 with gcc 3.

This patch remedies the problem.
