Right, I don't think this is a kernel problem, I tried it with a
2.4.29 kernel and the   intel card compiled  monolithic  in, the  same
behaviour. It does not work under 2.6.5 neither.

Yeah, I received a message from another R51 thinkpad user with the
same awful card (there are not very many users) and he recommend me to
use i810switch, which works, but the display is a little grainy. There
is also i855crt but this does not work for my chip set.

So right Matt  X.org is the thing to  go, the option you described are
for the i833 chip which is what I need.  However the last thing I need
Right  now  is  to  screw  up  my X  windows  system. I  found  a nice
description of  how to  have it installed  together with  XFree  under
Debian, maybe I give it a  try.  It seems  to me that no *mayor* Linux
distribution offeres X.org, which makes me think....

Thanks
