specifying your resolution is also included in `my' howto/procedures:

knoppix26 screen=1280x1024

would do the job during installation.

if you wish to specify it after you have installed the thing, you could edit /etc/lilo.conf, look for the ``append'' parameter, and include `screen=1280x1024'.

save /etc/lilo.conf, run lilo (`sudo lilo`), and that's it
