I use it on my Pentium-M laptop.  I don't need the latest KMS stuff, but
I do need X11 so that I can use a browser, vncviewer, and a few terminal
windows.  Falling back to VESA resolution would suck.  It's currently
running 11.0-STABLE. I'm planning on migrating everything over to 12.0
sometime after 12.0-RELEASE.

I have one other i386-class machine, but it only needs a text console.
Everything else here is amd64.
