It's not slow on a precise step, it's simply feeling slow overall. For
me it's not a surprise at all if the whole kernel runs from ST-RAM.
I was able to install the Etch image from
http://wiki.aranym.org/afs/setup_linux that was originally setup for
usage in Aranym, on one of my Falcon partitions; and run the 2.6.26
kernel using it.
If I remove the '-s' flag with the exact same setup, I hear the hard
disk spinning really fast loading all stuff, but (1) I only get a black
screen (2) it resets after a while.
Fixing the kernel to run it from FastRam seems top priority for me, to
have it run at full speed.
