FreeBSD vs Linux: more than 80 chars.

[Gianmarco]

Hi, the question is very simple.

I'd like to have more than 80 chars on my console.
My env is:
* Dell latitude D600
* FreeBSD 5.3-ALPHA
* ATI Radeon Lf R250 Mobility 9000 M9

My vidcontrol -i mode shows:

--> begin <--

---> end <---

I have removed any line different from the text mode and from 800x600.
The full output is here if needed :
http://www.gufi.org/~gmarco/files/vid.txt  

I have used  in the kernel:
options     VESA
options     SC_PIXEL_MODE

But I am not able to use any mode wider than 80 chars (and this is shown in 
the vidcontrol. Nor I am able to use any VESA_800x600 graphic mode.

Now I am asking here if am I missed something because some Linux distributions 
I boot seems to use graphical modes and/or more than 80 chars x line.

Thanks for attention.
