I came up with this as well, but used the machine_is() infrasturcture.

Subject: [PATCH] Run fixup code only on the appropriate platform.

commit a969e76a7101bf5f3d369563df1ca1253dd6131b (powerpc: Correct USB
support for GE Fanuc SBC610) introduced a fixup for NEC usb controllers.
This fixup should only run on GEF SBC610 boards.

Fixes Fedora bug #486511.
