A zillion thanks to John Baker for mailing this! I changed this
on my old HP Proliant DL360 G6 with its ATI ES1000 (RV100) onboard
graphics two weeks ago and --voila-- instant karma!
I get now the radeon framebuffer console with proper 1280x1024
resolution and clearly readable text (green, black, and white all
as they should be); X11 also improved: 640x480 vga/vesa before,
1280x1024 radeon gfx now.
Thanks again, Martin Neitzel
