Trouble with a atapi-cam backup..

Hi all:

So I finally upgraded my 7.3stable main server to 8.1stable...

And now my backup to atapi-cam is failing.. I get:

root_at_lakerest /usr/tmp]# /usr/local/bin/growisofs -Z /dev/cd0 -R -J  
backup_init.08-31-2010.gz
:-( unable to CAMGETPASSTHRU for /dev/cd0: Inappropriate ioctl for  
device


Now atapi-cam I have built into the kernel (not a loaded module).. and  
so is scsibus.. and all
its friends. Cam control seems to see the device:

[root_at_lakerest /usr/tmp]# camcontrol devlist
<HP DVD Writer 1140r FH23>         at scbus0 target 1 lun 0 (cd0,pass0)

Any suggestions of what I left out of the kernel  would be most  
helpful..

Oh my kern.conf is:

*****************************
include         GENERIC
ident		mymachine
device		atapicam
options 	IPDIVERT
options 	IPFIREWALL
*******************************

And its an i386

Thanks

R
