Problems with virtual terminal

Hi all,

I want to use virtual terminal to get tty support for using Xorg on a fb device.
I' m using linux-mips 2.6.12-rc4.
When I enable the virtual terminal option in the kernel config the kernel hangs directly after boot. The console parameter is set to ttyS0, so I expect some output on the serial port, but nothing happens.

Is there someone using virtual terminals?
Any ideas what went wrong with vt?

Beste regards
