I am currently running Debian 10.

sudo lspci|grep VGA
01:05.0 VGA compatible controller: Advanced Micro Devices,
Inc. [AMD/ATI] RS780 [Radeon HD 3200]

sudo xrandr

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
VGA-0 connected primary 1440x900+0+0 (normal left inverted right x axis
y axis) 408mm x 255mm

1440x900      59.89*+  74.98  
   1280x1024     75.02    60.02  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   640x480       75.00    72.81    66.67    59.94  
   720x400       70.08  
HDMI-0 disconnected (normal left inverted right x axis y axis)

So I boot the debian 11 live iso from usb and it only offers me three of
the lowest resolutions. I think what I need to do is tell the kernel
command line to install the radeon driver, or maybe copy an xorg.conf
file onto the live root but I cannot find any such file, no file which
contains 1440x900.

How can I get 1440x900 with the live cd?
