I realize that fb consoles are possible, but if
I wanted my old AMD K6-2 spend its cpu time
copying pixels to video memory, I could just have
used X (there are fast window managers out there).
What I wanted to know is if there is someone who
knows this stuff well enough to program a little
utility which sets the dot clock .(At the moment,
I use the BIOS to set it to 40MHz by selecting a
text mode which uses this dot clock, and make sure
that svgatextmode does not touch if further. This
gives me a 100x30 character console, which is not
too bad. However, being restricted to 40 MHz dot
clocks is a bit unsatisfactory.)
Still thanks for the answer.
