Guess that's no longer really needed, but here are the relevant lines from a dmesg diff between kernels with and without FB_CONSOLE_DETECT_PRIMARY. Command line: root=/dev/sdb1 ro [...] Console: colour VGA+ 80x25 console [tty0] enabled [...] checking if image is initramfs...<6>Switched to high resolution mode on CPU 1 Switched to high resolution mode on CPU 0 [console output stopped here] it is [...] (omitted about 30 lines) -Console: switching to colour frame buffer device 80x25 -fb0: Virtual frame buffer device, using 1024K of video memory Thanks for quick reaction.
