I have a CB264.

I assume it's complaining because it doesn't know how to open the card's
driver, actually.  (That's what that error says to me, at least.)

I groveled through the card's interrupt handler until I found what I was
looking for.  I'm certain I have some code around here somewhere that will
handle the interrupt, but it's very CB264-specific, unfortunately, and I
will not be putting it into the source tree.  I'll append it to this
message; it's an older diff but should be pretty trivial to add
regardless.

In my experience, Cabletron uses mostly standard parts in extremely
non-standard/annoying/EVIL ways, so that you have to use their proprietary
driver.  This is a tactic that IBM used to play pretty heavily with, and
in some sectors, they probably still do to some extent.  (OK, so it's not
really -evil- but it's certainly no way to keep customers these days.)
