Can you force the kernel to dump by using DDB? Place 'options DDB' in your kernel config, then, when the system is quiescent, hit Ctrl-Alt-Esc and type 'panic' at the DDB prompt. If this works, and you get a crash dump, then the problem might be that with your kernel patch, the kernel is panicking in a low-level layer, like memory management or disk drivers or something like that, and it simply cannot make a crash dump, since that would mean invoking code that depends on bad data or something.
