Must I partition a new disk to give more space to /, or can I find more space by deleting /stand/, /modules/, and possibly /rescue/ to shoehorn a custom 7.x kernel in the available space?

Right, the numbers I quoted were for an opt-in system like tinybsd... They are good numbers to have at hand, since it is hard to buy flash media that's smaller than 1GB these days... Warner
