Your card can't accelerate 24bpp for anything more complicated than 2d
source copies, only 24/32 depth with 32 bpp, so you're actually at
32bpp.  Also, front, back, and depth buffers are allocated statically at
startup all with the same bpp, so there are 3 buffers.  So, width *
height * 4 * 3 is how much you need.

(These logs posted here are different from what was initially posted. 
I'm still curious as to what was happening previously.)
