Xircom did put them up on their web site sometime back in 1999, right
before they were bought by Intel.  It had some kind of click-through
licence and was quite hard to find.  No idea if it's still available.

I had a look through the manual and I agree entirely with Werner.

I'm surprised nobody has noticed this problem before now -- the driver has
been in -CURRENT for ages, although I didn't use it myself until last week.

Anyway, I hope the patch can be committed soon, as it seems like it would
solve this problem.
