Darn, that was with xf86-video-intel not built for valgrind so valgrind doesn't
understand the allocations/usage of video memory. Can you please build
xf86-video-intel with ./configure --enable-debug --enable-valgrind ?

Even if it does not crash with valgrind, valgrind probably detected the error.
Probably. (There are a number of causes (from using the GPU) that valgrind
could not and simply changing the timing would be enough.) But since this
sounds i-v-o related, I expect valgrinid to catch the error.
