there are a few graphics cards/chips (at least DEC TGA, and I think monochrome cards like Hercules too) where the kernel (card?) doesn't support text scrolling yet. at least for them having a generic software method to scroll text VCs would be a *big* benefit. having this software method, one could define the scroll buffers as large as needed (and vice versa;).
but keep in mind that this all goes into non-paged kernel memory and having 8 VCs with 1000 * 132 character lines is another MEGAbyte you're loosing...
