Description:

I'm using an advantech pcm3350 SBC.  I have reinstalled SuSE
8.0 with a minimal set-up (no X and yes to minimal system).  About 250Mb
was installed.  Then I installed Xfree86 4.3.0RC2 using the Xinstall.sh
script.  No errors and so on.  Then I copied the XFree86Config file from
the previous setup (including the nsc module).  When running startx
everything was functional at 1024x768 16bpp.  The windows manager is twm.

When I use CRTL+ALT+Fx  the screen flicks and goes to dark black.  No
characters -nada-.  When I press CRTL+ALT+F7, the graphics are back again.
If I pay attention, the consoles appears for a fraction of a second before
switching to graphics, so the memory is not corrupted.

I have changed the "nsc" line to "vesa" line, and the consoles and
graphics are ok again.  I can swith between them without corruption.  When
I put back "nsc" the black screens are back again.  So I believe the
problem is with the nsc driver itself.

I have moved the kernel from 2.4.18-SuSE to 2.4.20-SuSE and the behaviour
is the same.

I have checked and I have framebuffer configured in the kernel (SVGA
compiled in and others as modules).  I know since SuSE puts the kernel
config file in /proc/config.gz

I do not have the FULL SERVER OUTPUT right now but no error is reported. I can get it 
but it is a Single Board Computer so I not trivial. 

Repeat By:

With the nsc driver loaded, swith consoles using CRTL+ALT+Fx and I get only black 
screens.  CRTL+ALT+F7 returns to graphics console.

The Xserver is up and alive since I can export DISPLAY.
