Thanks, the text console is now more or less working as expected.
There is still an issue with the cursor, though.
After doing "echo hello > /dev/tty0", the text appears, but the cursor
is gone. "clear > /dev/tty0" brings it back.

The execution time of "time ls" has improved. It now takes 1.21s
(0.86s with ssd1306fb).

The logo is not shown, even when I create a 16-color or 224-color
version of the small monochrome logo I'm using.

Gr{oetje,eeting}s,

                        Geert

when I'm talking to journalists I just say "programmer" or something like that.
