Why is that so?
My Dell 2000FP, which is natively 1600x1200, made January 2003, does all
supported modes over both D-sub and DVI using various ATI, Intel & Nvidia
gfxchips newer than yours. I don't have any Mach64 cards I could try though.

I dont' know that mach64 was ever supported by the "ati" driver. A mach64
driver is on the mirrors, and almost certainly requires KMS be disabled.

Is that gfxchip on the motherboard? Does it have an empty PCI or video slot?
Something newer might be easier than making that chip work.

It might help troubleshooting to cut down that cmdline down to only what's
needed and leave the messages on tty1, maybe like so:
root=... showopts noresume splash=0 vga=normal video=1024x768 at 60 nomodeset
With showopts near the front it's easier to tweak on the fly, change vga= or
video= or remove video= or nomodeset.
If the mach64 is already installed, and you've tried with both nomodeset on
cmdline and with no xorg.conf together, try an xorg.conf with no more than
the following in it as a starting point:
# HorizSync 31 - 80
# VertRefresh 56 - 76
# Option "DDC" "off"
# Option "DPMS" "off"
# Option "DefaultModes" "on"
# Option "PreferredMode" "1024x768"
Option "Composite" "Disable"
If not good enough, try removing the comments. Modelines with Xorg I've never
ever needed, no matter how old the gfxchip.
