yours only goes to 64MB?

Yep, this is from my BIOS dump:

not sure but maybe something like:

It seems that this guy's BIOS had higher DMVT Pre-Alloc options like 512MB and 1024MB, which is not my case.

I wonder if it's still technically possible to push the framebuffer settings beyond and above the BIOS' max DMVT. I'll open a new thread for this question.
