working with dbsd-tools

[Jonathan Horne]

i almost have desktopbsd tools working perfectly... except that i cannot mount 
usb drives without opening a terminal as root, and chmoding /dev/da* to 660.

how can i cause new devices (such as da*) to be created with proper 
permissions to let me mount it without becomming root to do so?  ive already 
set up my devd.conf, and cdrom is working (but that one doesnt 
disappear/reappear like usb devices do).

thanks,
jonathan
