Hi Mich & all others,

Rather sure, but I can't test it now because I switched my PBG4 12" HD
from hdc -> hda ;) (only with 2.4.21-rc*-ben0 possible). So I can't
use that 2.4.20-ben*. IIRC there was _normal_ console speed by default.

It gives:

    # D: 65.003 MHz, H: 48.365 kHz, V: 60.006 Hz

endmode

But as I mentioned, console slows down during boot at that moment,
when  the penguin disappears (which is awesome from an esoteric point
of view ;))  )

THX again and a nice evening
