Hello,
I had a k panic some hours ago but I think that's related to a problem with one
of my HDs.
I've got a dump in /var/crash, and as you were interested, I run:
# kgdb /boot/kernel/kernel /var/crash/vmcore.6
GNU gdb 6.1.1

This GDB was configured as "i386-

Terminated
I had
to pkill kgdb as it was in a loop.
Running it against kernel.debug in
/usr/obj/usr/src/sys/$KERNCONF/ worked as expected.
I've always followed this
way, so I don't know if it was working with earlier releases.
