rebooting vs kldload?

[paul beard]

On this page, the following text appears:

This driver allows ATAPI devices (CD-ROM, CD-RW, DVD drives etc...)  
to be accessed through the SCSI subsystem, and so allows the use of  
applications like sysutils/cdrdao or cdrecord(1).

To use this driver, you will need to add the following line to the / 
boot/loader.conf file:

atapicam_load="YES"
then, reboot your machine.

Is there any reason why one can't load the kernel module manually, at  
least for testing, without rebooting? I was able to do that just to  
satisfy myself that it camcontrol could see what I hoped it would.
