My own experience with 24bpp on the SS20 says that you probably will
care about at least 2D acceleration once you experience
dumb-framebuffer 24bpp speeds.  There's a reason I wrote dual-depth
code for the cg14!

Yeah, high-res cg6s are nice.  I need to sit down with them and figure
out enough to change the video mode at runtime after NetBSD boots.

I see you like understatement. :-)

I will echo what Joshua Boyd said and urge you to make sure you have
good cooling.

I had a ZX once.  I may still have it, though if I do I don't know
where it is.  I'd love to find enough documentation to write 3D code
for it; it looks to me from the little doc I have found as though it
has a 3D transform engine, depth buffer, and similar things that make
it remarkably 3D-capable for something from its era.
