Why isn't there a driver attached to this device?

[Kevin Oberman]

Very odd. Oddly, I didn't find any source files and the module was in
/boot/kernel.old. I'm simply baffled as to how it got there. It is dated
02-Feb, so it's from my last build. Best guess is that it was pulled for
some reason. With SVN, I'd look at the sources as of 2/2/21, but I'm just
starting on git. Perhaps you might have some idea for tracking it down.
Perhaps I botched a pull and got main branch instead of stable/13. I'm
certainly running the correct version today.

Sorry for the confusion.
