AFAIK it enables you to (simply) change the text screen size and
refresh rate from the standard 80x25 to whatever you want, and is
therefore responsible for SVGATextMode freezing in 1999.

Yes. Every character sent to the screen is sent as a bitmap. How
significant this is depends on the speed of your machine and your
sense of engineering elegance. It offends mine, so I use SVGATextMode,
even though that meant some hacking to get it to work with a SiS6326.

Try vga=0 in your boot parameters (I think, I've never turned it on).
IIRC it's a kernel feature which my kernel is compiled without.
