Update.
This guy made a better svga driver: https://github.com/PluMGMK/vbesvga.drv
So, I f'd around and added it.

1) unless stated otherwise the above list applies
2) I set the default to 1024x768x8bit.
3) There are only 4 display modes in the initial setup because the inf was a pain in the ass
4) Workaround: copied "oem0.inf". modes changable in "Windows setup".
5) added shortcut to show the available video modes before you change it "Video modes"
6) Keep an eye on that github page. New versions are likely.
7) If they do updates, copy files into windows dir, and (if he makes one) rename oemsetup.inf oem0.inf
😎 feel free to edit oem0.inf - it should be fairly self explanatory to add whatever random missing modes your setup supports that I left out.
9) To add VESA modes to Oracle virtualbox: C:\Program Files\Oracle\VirtualBox>VBoxManage setextradata 311"CustomVideoMode1" "1920x1080x24"
(311 is the VM name)

Edit Opps.
Accidentally removed the tcp/servicepack stuff
Fixed
