This entry is being used for tracking a regression from 2.6.25. Please don't
close it until the problem is fixed in the mainline.
Just to confirm, here is the report sent to the lkml:
The system boots fine with 2.6.26-0.rc3.1mnb (Mandriva Cooker), but since rc4, I see a few squares of color, then a black screen and the console never comes back. This is independent of the resolution chosen when using vga=ask. The machine does boot and I can start X if I log in blindly. Only the F1 to F6
consoles are gone.
Bug originally reported and ignored on Cooker: https://qa.mandriva.com/show_bug.cgi?id=41302
My card is an old STB NVidia Riva TNT, monitor is a flat panel Dell 2007FP, system is a Dell Dimension XPS T600 (82371AB/EB/MB PIIX4 with PIII 600).
I cannot see anything different in /var/log/messages between rc3 and rc4 (vga=837)

This is still true with a vanilla 2.6.26-rc8.
$ grep FB_RIVA /boot/config
# CONFIG_FB_RIVA_I2C is not set
# CONFIG_FB_RIVA_DEBUG is not set
Is it better now with 2.6.27-rc8? I think not.
Otherwise it'd be easy to bisect between 2.6.26-rc3 and 2.6.26-rc4.
