If there is 1.6K overhead per vt coming from somewhere (given we only preallocate 1 VT) then either
- There is stuff not being dynamically allocated (which you can find and fix)
- Your userspace is triggering those dynamic allocations
There is no magic thing that requires 1.6K of kernel data per console.
