I got that pause when running it as well. Seems that the memcpy from
video memory is what causes this. Do you (or anyone else on the list)
know why reading video memory takes so long? I have a Radeon 9200 on an
ASUS A7V133 motherboard.
I modified fbtest so that it doesn't bother saving or restoring if the
console was in KD_TEXT as it will get restored by the console anyways.
This go rid of the pause. I'll post those patches once I test it with
the normal VGA console.
