Yes, by 25x25 puzzles I mean sudoku puzzles with 25 cells on each side,
with the smaller squares being 5x5 (i.e., we need to construct rows with
the numbers 1-25, and the smaller squares must each contain all of the
numbers 1-25).

Question: what do you mean by, for example 25x25? Do you mean grids with
a total length of 25 on each side, eg:
(because on my super-dooper 1.66GHz Celeron, generating 10 random 25x25
grids such as the one above takes about 1.01 seconds; solving an actual
puzzle should be faster because the solution space is more tightly
constrained?)
