I was able to reproduce it with SqlClient (got a FormatException). The problem
does not appear to be (Sql)CommandBuilder - as the update command we generate
exactly mathes MS - but with the way DbDataAdapter.Update determines whether a
given parameter is a "nullCheckParam".

I *think* it should be easy to fix on the 2.0 profile (as we have
DbParameter.SourceColumnNullMapping to determine whether it's a
"nullCheckParam"); not sure how to accomplish this on the 1.0 profile.

I'll try to have a closer look tomorrow. I also think bug #421336 may be a
duplicate of this one.
