what about titan 8-port PCI boards?

would it be usable in netbsd. on chips 16c950 or 952 is written (don't
remember exactly), on linux is detected as 16650V2 and works fine, setting
it manually to 950/952 makes transmission control lines not working right.

wherever you like and then set com* lines for that.
