I think I may have found a way to do this:
'The kernel does not boot:
If your new kernel does not boot, or fails to recognize your devices, do not panic! Fortunately, FreeBSD has an excellent mechanism for recovering from incompatible kernels. Simply choose the kernel you want to boot from at the FreeBSD boot loader. You can access this when the system boot menu appears. Select the “Escape to a loader prompt” option, number six. At the prompt, type unload kernel and then type boot /boot/kernel.old/kernel, or the filename of any other kernel that will boot properly. When reconfiguring a kernel, it is always a good idea to keep a kernel that is known to work on hand.'
Is this what I should do to get this current kernel set as the default? Or shall I just get a new copy of the GENERIC kernel and start again with the recompile? The reason I say this is that the GENERIC kernel has been broken.

Trying to force it with amd options nfs_proto=tcp and so on.

NAME
uchcom -- WinChipHead CH341/CH340 serial adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:

device ucom
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
uchcom_load="YES"
DESCRIPTION
The uchcom driver provides support for the WinChipHead CH341/CH340 USB-to-RS-232 Bridge chip.
The device is accessed through the ucom(4) driver which makes it behave like a tty(4).
HARDWARE
The uchcom driver supports the following adapters:
o HL USB-RS232
SEE ALSO
tty(4), ucom(4), usb(4)
HISTORY
The uchcom driver first appeared in NetBSD. The first FreeBSD release to include it was FreeBSD 8.0.
BUGS
Actually, this chip seems unable to drive other than 8 data bits and 1 stop bit line.
