The blit stride is a two's complement 16 bit number, so trying to
use a stride of 32k would in fact give us -32k. Not sure how this
ever worked on anything, but my 945gm sure doesn't like it. The
machine dies pretty much instantly. Let's reduce the blit to use
a 16k stride instead. Also put in the missing bits for a proper
32bpp blit.

Or maybe time to retire this test since we no longer use CS flips?
