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.

Ping!

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.
