The console fonts aren't scalable – each font file in
/usr/share/kbd/consolefonts has exactly one size AFAIK. So there is no
point in having a separate fontsize option because that's already part of
the file name (fontname).

For example, if you install the Terminus font, you select the size using
FONT=ter-v20n, FONT=ter-v22b, FONT=ter-v24n, etc. It's up to each font to
provide these variants.

(The largest "stock" font is probably sun12x22, but its charset coverage
isn't great.)

The kernel will activate a framebuffer automatically as soon as a KMS video
driver is loaded (such as i915 or radeon). You can specify the screen
resolution using the "video=1024x768" kernel boot option (e.g. via GRUB).

This doesn't require systemd-vconsole and generally happens automatically
as soon as udev starts. (Possibly even during the initramfs? I use
early-KMS on Arch, no idea how that's done on SuSE.)

On the other hand, if you're using the proprietary nVidia drivers, I'm not
sure if those support a framebuffer at all?
