You mean machines made today?

Yep, I remember having to use --force-architecture to install the Linux 
kernel from the 64-bit version of Ubuntu into the 32-bit version.
As I remember, the package name was the same as the 32-bit version, causing 
confusion.
What led me to uninstall it, though, was that suspend/resume did not work 
properly.
I am adding a CC to the Ubuntu kernel team mailing list.
