Its not the puc per se as the transition from sio to uart
from /usr/src/UPDATING
20080713:
The sio(4) driver has been removed from the i386 and amd64
kernel configuration files. This means uart(4) is now the
default serial port driver on those platforms as well.
To prevent collisions with the sio(4) driver, the uart(4) driver
uses different names for its device nodes. This means the
onboard serial port will now most likely be called "ttyu0"
instead of "ttyd0". You may need to reconfigure applications to
use the new device names.
When using the serial port as a boot console, be sure to update
/boot/device.hints and /etc/ttys before booting the new kernel.
If you forget to do so, you can still manually specify the hints
at the loader prompt:
set hint.uart.0.at="isa"
set hint.uart.0.port="0x3F8"
set hint.uart.0.flags="0x10"
set hint.uart.0.irq="4"
boot -s
