When I enable the shader modpack in minecraft my computer locks up: keyboard
does not react and screen has dark/light gray stripes.

You need to install forge and those two mods in order to reproduce the bug:

I tried it without DPM, without HyperZ and without both, but the lockup didn't
change.

I am using Gentoo:
- with kernel 3.14.14 and mesa 10.2.4, the screen started flickering (on/off,
on+black/on) and locked up eventually.
- with kernel 3.14.15 and mesa 10.2.5 it immediately locks up and leaves me
with gray stripes.
