Hmmh, it looks like 8-bit-video...; 
Here is my fbset-output: 

mode "1024x768-60"
    # D: 65.032 MHz, H: 48.387 kHz, V: 60.034 Hz
    geometry 1024 768 1024 1020 32

I chose vmode:14 (60Hz vertical refresh) because that is fast enough for
a 15" 1024x768-LCD-screen. You can set video modes as kernel boot
options in your bootloader somewhere (I use an old world mac, so I don't
have any experience with the yaboot-bootloader, just with BootX), I use:
video=atyfb:vmode:14,cmode:32 

"atyfb" is probably still in charge of the ati rage 128 (for
consolevideo), but I am not sure. There is a XF4.2-driver called "r128"
which should support your ATI Rage 128, xconfigurator should write the
correct driver settings to your XF86Config-4.;

No, you have to run fbset with one of these options: -x or --xfree86,
then it looks similar to this... I think the dexter.py-script runs
xconfigurator and xconfigurator actually runs that command and feeds its
output to XF86Config-4.
