No. The broken one is still broken if I disable alignment fix-ups.

Ooo, thanks for that. :)
I've attached the dmesg output.

All the errors on boot seem to be coming from 
/lib/udev/devkit-disks-part-id.

# rpm -qf /lib/udev/devkit-disks-part-id
DeviceKit-disks-009-3.fc12.armv5tel

yum updating this  (and the 13 dependencies it has) from the F13 
repository doesn't make the problem go away. :(

Thankfully, though, nothing on the Sheeva uses this. I'll try rebuilding 
the latest version of DeviceKit from source and see if that makes the 
problem go away.
