1/ Better to keep the GENERIC configuration file not touched. Copy the
   GENERIC file to a new file named "the-name-of-the-machine-in-upper-case"
   (ex.: FBSDBOX) and changed the 'ident' entry according to the new name.
2/ Add the device atapicam at the end of the file.
3/ Clean up the obj directory.
4/ Build and install the new kernel.
5/ Reboot.

*Example* of the steps:
# shutdown now /* In order to go to Single User Mode */
# cd /usr/src/sys/i386/conf
# cp GENERIC FBSDBOX
# diff -u GENERIC FBSDBOX

Note that the last build/installed kernel is backuped automatically when
installing a new kernel, so you can always boot specifying the last known
working kernel at boot time if the new one isn't working as expected.

Another good place to start is:
 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/\
 kernelconfig.html
Particularly (for your last point):
 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/\
 kernelconfig-trouble.html#KERNELCONFIG-NOBOOT
