xorg.conf for legacy G3 imac with ATI Riva128

Hi,
after spending a few nights trying to figure out how to get ATI drivers working, and staring at newer and exotic Xorg error messages, I eventually found a working setup. I thought I'd post it here for records, and in case it could help someone.

Section "Device"
    Identifier      "Rage128PR"
    Driver          "ati"
    BusID           "PCI:0:16:0"    # values are DECIMAL
#    VideoRam        8192            # may not be needed since it usually detected
#    MemBase         0x94000000      # obtained from 'lspci -vv' output
#    IOBase          0x0400
        Option      "UseFBDev"      "false"
        Option      "NoInt10"       "true"
#       Option      "DMAForXv"      "enable"  # Use DMA for XV, reduces CPU usage
EndSection

Section "Monitor"
    Identifier      "iMac Monitor"
    HorizSync       58-62
    VertRefresh     75-117
EndSection

Section "Screen"
    Identifier      "Default Screen"
    Device          "Rage128PR"
    Monitor         "iMac Monitor"
    DefaultDepth    24
    SubSection "Display"
       Depth     24
       Modes     "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

Section "Module"
    Disable "glx"
    Disable "dri"
EndSection

Section "ServerLayout"
    Identifier "Default Layout"
    Screen "Default Screen"
EndSection

This is an imac 350 Mhz, running Xfce decently (184 Mb RAM - hoping for more - and 8 Mb video card).
So far only Xfce display settings don't work. I get something like "cannot launch screen configuration window. Driver does not support video outputs". No big deal.

Cheers.
