Ok, I found it in that Wikipedia article:
Modes 264-268 (vesa's numbers, not the kernel's) are text modes.
264 (0108h) is 80x60, 265 (0109h) is 132x25
266 (010Ah) is 132x43, 267 (010Bh) is 132x50
268 (010Ch) is 132x60.

Well, I use the framebuffer @ 791. I have never heard of the
vga=10 that you mentioned. All the modes I have seen are over 700.
I guess the lower ones are text modes (not sure how they relate
to vesa's numbers).
The Debian kernels have the framebuffer drivers compiled in, so
I would just try vga=791 and see if it gives you what you want.
You also mentioned speed. I don't know how fast your computer
is, but I have used 791 on a P3 @ 700 MHz and it was fine.
