Is there a rc.conf variable to automatically save core on a panic and reboot ?
Setting dumpdev="AUTO"  doesn't seem to do the trick.

dumpdev merely controls which swap device the dump gets written to.
You probably want to either compile your kernel with KDB_UNATTENDED or set the debug.debugger_on_panic sysctl to 0. (I run my systems to drop into KDB interactively, but reading kern/kern_shutdown.c seems to indicate that this will do what you want.)
