I would think this is not a problem with debian-live as such but the
mach64 video driver.
In general knoppix and debian-live probably use a slightly different
mach64 driver and have different bugs.
This driver is ancient and not much used anymore so there might be
some issues. Unfortunately my system with mach64 video card has no
CD-ROM nor can it boot off network nor USB so I cannot test easily.
I suggest looking at the X logs and find why X is choosing 800x600
mode over 1024x768.
You should be able to list the modes X supports and change between
them with the xrandr command.
Note that on debian-live you can also install new packages so you can
try different X versions (enabling swap is suggested on older systems
so that you do not run out of memory).
