I use ssh to log in to a console server, hit enter and
am connected to the console. I have no idea what kind
of software is used between console server and console.

Yes, together with the other options you suggested:

makeoptions     DEBUG=-g
options         DDB
#options         KDB_UNATTENDED
options         KDB
options         BREAK_TO_DEBUGGER
options         WITNESS
options         WITNESS_SKIPSPIN
options         INVARIANTS
options         INVARIANT_SUPPORT

The ssh man page offers:

|~B      Send a BREAK to the remote system (only useful for SSH protocol
|        version 2 and if the peer supports it).

I am using ssh 2, but the only reaction I get is a new line.

|FreeBSD/i386 (tor.fabiankeil.de) (ttyd0)

|login: ~B

Maybe machdep.enable_panic_key would be another solution?
The description says "Enable panic via keypress
specified in kbdmap(5)", I'm just not sure if console
input qualifies as "keypress".
