I've been through a couple of update cycles on current and installed
the latest kernel and sets. Now "com0 at isa?" in my custom kernel
doesn't work either.

While connected to the port, with a known active data source at the
other end, I can press <return> and the interrupt count goes up by 2.
If anything is being received, it's not showing up on my terminal (urxvt).

Will reboot with a GENERIC kernel shortly to check.
