I like Linux.
I like OpenGL.
I don't like X.
On Linux, is there anyway to get 3D acceleration from my Nvidia card without X? Ideally, I'd have the kernel boot, get to a console, then somehow get into a "graphics mode", where my entire monitor is just a single OpenGL screen ... and I draw stuff to it with OpenGL. Without X. Is this possible?
Thanks!

Well it should be possible to use the framebuffer with hardware acceleration, see here.

Nvidia's binary driver only works with X. You can, however, run a headless X server. See the section on "UseDisplayDevice" "none" in the README:
ftp://download.nvidia.com/XFree86/Linux-x86/190.36/README/appendix-b.html#UseDisplayDevice
I believe the future Gallium + nouveau stack will work sans X, but it's still under heavy development now.

Wikipedia has a section on Competitors to X.
Among them, a possible match for what you want is DirectFB, but it says that "The Direct Rendering Infrastructure [which is in X] ... may make these efforts redundant"
Unless you plan on writing your own operating system and then writing the applications on top of it, I would recommend sticking with X. It's been developed and used for decades, and I'm pretty sure there isn't any good replacement for it out there.

From everything I can find it looks like OpenGL needs X.
