Do you have fb support in the kernel?

Do you have modeline2fb utility? I believe it is in same package as
fbset. When I run it on your modeline, I get the following, suitable
for entry in /etc/fb.modes:
# modes.fb - video mode descriptions for fbset
#
# See fbset(8) and fb.modes(5) for more information
mode "1280x1024"
geometry 1280 1024 1280 6537 8
timings 7407 192 64 55 3 192 3
endmode
If you get to the point where you can see anything, adjust the
picture with the controls on your monitor. Stretch the screen to the
right size etc. Then run fbset with no options; it will output the
current mode which you should then place in /etc/fb.modes.
A command like fbset -a 1280x1024 will set all vt's to use that mode
from /etc/fb.modes.
