No, that's exactly the kind of thing I'd expect to see from /proc/fb.

The xserver-xfree86 config script interprets this as "kernel framebuffer
device unavailable" -- isn't that correct?

Could you propose a better test?  What will /proc/fb say when someone is
using a generif framebuffer device like vesafb, OFfb, and so forth?

I can write the string parsing; just tell me what values I need to
ignore.

Also, I assume that anyone using a generic framebuffer needs to be using
the "fbdev" XFree86 *driver*, right?
