Bank screen after resume on Dell XPS M1330

[Andrey Borzenkov]

I am struggling with new pet. One of the issues is that resume seems to 
work but display is blank. I can blindly enter commands (e.g. to cleanly 
reboot) so system is perfectly alive - just no output on LCD.

This happens on both 2.6.29 and 2.6.30-rc4 in both 32 and 64 bit 
kernels. Also it happens using init=/bin/sh which at least rules out any 
video driver issue.

lspci follows just in case. I am open for any patches and suggestions :)
