In previous installation attempts I have this same problem - I reboot to a blank screen (my moniotor shuts off).  I was hoping that after the updates, I wouldn't have this problem, but here I am again.

For the 2nd question, you can choose "ATI Radeon 7500" as videocard-type
and "radeon" (important) as "Dique" (french language) under the display
(videocard) advanced parameters ; after that, you can step by step
increase the colors-number to the max supported from your monitor.

For the 1st question, i know that it's possible under GRUB, but don't
know how (am using LILO).

                                           good luck,
