Yes, you should see output in dmesg (and /var/log/messages if
syslog.conf is in the default configuration).

But you have to also turn on some debug via sysctl...
sysctl compat.linux.debug=all.1

all.0 to turn it off, or something other than all to control debug
output for a particular call... see sys/compat/linux/linux_mib.c
and sys/<arch>/linux/linux.h
