Uh-oh. 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.
