I'm not sure how it is implemented at the graphics card level, but the Linux kernel virtual console can be high-resolution. The "correct" thing to do here is set the console font to a larger one. If you are on a systemd-using distribution, see vconsole.conf(8). Now, you could force a lower resolution, but that causes jaggy text, as pixels will be stretched unevenly by the graphics card. This can be done with KMS, or the vga= boot parameter.
