When I do this I get following:
.....
There is absolutely no warranty for GDB.  Type "show warranty" for details.
This GDB was configured as "i386-marcel-freebsd"...(no debugging symbols
found)...
(kgdb) list *0xc0751582
No symbol table is loaded.  Use the "file" command

Looks like I need to rebuild kernel for debugging support can you help me
what module needs to be loaded in the Kernel configuration when recompiling
it? Or can I dynamically via kldload make it happen?

thanks
Juris
