I get:
Jun 4 08:54:49 debian kernel: [ 0.000000] Console: colour dummy
device 80x25
Jun 4 08:54:49 debian kernel: [ 0.231537] Console: switching to
colour frame buffer device 128x48
and AFAIK those refer to the number of characters per x and y axis on
the console.

But xdpyinfo shows nothing about the console:
dimensions: 1280x1024 pixels (296x236 millimeters)
resolution: 110x110 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32

My VT consoles indeed are 128 characters by 48 lines.
I use NVidia's 195.36.24 and:
