I can confirm that, with the patch from 
http://lists.freedesktop.org/archives/intel-gfx/2008-November/000614.html 
applied on top of current git head (rejected hunk in 
drivers/gpu/drm/i915/915_irq.c due to the additional 
dev_priv->irq_mask_reg = ~0; in git between the removed lines, I kept 
it) I can suspend/resume and do a VC switch again.

Big thanks!

Bernhard
