vt_console_init() is very early function and must start only
single bootmem_alloc console. Later kernel call vty_init()
and add additional consoles, when kmalloc()
is ready. dummycon.c uses dumbcon_add() for this case.

Special for You dumdum module was created. Please
boot in to Your target kernel and try load dumdum module :)
cd dumdum
make
make install
modprobe dumdum
I You doubt please add some printk.

I am so sorry , but dumdum is untested.
