There is a bug in the linux kernel 2.6.35, that makes suspend to ram
unusable (it seems to be fixed in 2.6.36-rc2) [1]. The symptoms are:
- Suspend to ram from X hangs the computer, the only option is to press
  the power button for ~5 sec and thus forcefully turning off the  
  computer (SysRq does not work for me). After a while (when not
  turning off the computer of cause) the fan goes to full power.
- However, suspend to ram from console works.
- The hang does happen every time on my laptop. However,  on some
  computers that seems to happen only sporadically.

The link [1] contains two possible solutions for this problem.
1. Turn off BSD completely by replacing the corresponding define
   in i915_drv.h with
    #define HAS_BSD(dev)            (0)
2. 2.6.36-rc2 seems to fix the problem (according to a comment on [1]).
