I was delayed in getting to try some of the ideas out
and I eventually used the combination of setting HV in the
BIOS and adding vga=3D6 to my grub boot line. This gets me
full screen, however as soon as debian runs console-tools during
boot the video mode reverts to the original font size. At
least it is full screen in the vt's though.

I looked at the console-tools config docs and decided
the documentation was such that the learning curve
was too steep for too little value as there is no
real cookbook entries to do the simple things and
quite a lot seems to depend on having deep knowledge
of several applications and standards.

However, my vt is now at least as good as it was on the=20
t22, so I can live with that.

Thanks to all who gave advice.
