Okay, csup'ed, applied all.5.1.patch, recompiled kernel and 
rebuilt/reinstall supplementary stuff.

Results are the following:
- video is played w/o any issues (machine didn't freeze);
- vt switching behaves as in my previous post;

Also not sure that X actually operates w/o acceleration: the following 
output makes me think so:

# env LIBGL_DEBUG=verbose sh -c 'glxinfo 2>&1' | egrep '(render|Driver)'
direct rendering: Yes
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
     GL_EXT_vertex_array_bgra, GL_NV_conditional_render,

Additional information:
- pciconf -lvb: http://pastebin.com/YT8wUBiZ

- dmesg output (with DE effects enabled, leads to garbled screen):

- dmesg output (failsafe DE session): http://pastebin.com/f4gghA6E

- and just in case X logs (with ModeDebug="true"):
