Adding ed@ to CC list, since he maintains uart(4), which is now the
default serial driver on 8.x.
Michael, in the meantime can you provide dmesg details that pertain to
your serial ports? uartXX devices would be sufficient, in addition the
device its attached to (e.g. acpi0, etc.).
(Footnote: I wasn't even aware people still had/used serial mice any
more, given the popularity of PS/2, and now USB...)
