I just got a kernel panic after making /usr/ports/x11/nvidia-driver.
I did a make, make reinstall. Then I did a kldunload nvidia.ko
and got:

nvidia0: detached
panic: malloc(9)/free(9) confusion.
Probably freeing with wrong type, but maybe not here.
Debugger("panic")
Stopped at Debugger+0x54:  xchgl   %ebx, in_Debugger.0

trace shows:
