Bad news everyone!
Let me just explain by pasting from cli, logs and gdb.
First error:
bamse# kldload uplcom
kldload: can't load uplcom: Exec format error
Dec 22 14:23:22 bamse /kernel: link_elf: symbol usbd_abort_pipe
undefined
However:
bamse# kldload usb
bamse# kldload uplcom
ucom0: Prolific Technology PL2303 Serial adapter (ATEN/IOGEAR UC232A),
rev 1.10/ 2.02, addr 2
bamse# cu -l ucom0
Connected.
Second, a panic during 'kldload usb':

Unfortunately, I'll be leaving for Christmas holidays tomorrow and won't
have physical access to this machine until the 29th, but I'll be able to
log in the meantime.
