ex(4) is a fairly old driver in the tree that isn't supported by Intel for hardware that really shouldn't be used with -current.
I propose removal of the driver in two weeks. If there is no objection, I will do this.

I use this for PC Card testing. The driver still works, although it is slow.

Closing issue as it is still functional and still testable by others in the community.
