Impossible. Do you use multihead, or do all your ttyS belong to /dev/fb0? If you are using /dev/fb1 (but you should do it anyway...) please apply patch from ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/fbset-through-vt-2.4.19-rc5.gz to your kernel. Besides that it fixes (oopses|kernel corruption) if you do 'fbset -fb /dev/fb0' while you are watching console on /dev/fb1, it also allows you to do 'fbset -fb /dev/tty*' - this could simplify your script a lot. And no, patch is not going to the kernel. James vetoed it years ago... And while you are on it, please try ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/mga-2.4.19-rc5-tvout.gz too. But I believe that fbset-through-vt patch will fix your oopses, and this mga patch will not bring any new feature to your old MGA.
