I'm using Crux Linux 2.7 (32bit) with a vanilla kernel 2.6.37 from kernel.org.
I have an Intel G33 onboard graphics chipset and an Asus VW222U monitor
attached via DVI. When the kernel starts the monitor is turned off as it does
not get a signal from the computer. The X Server started later on does not
activate the monitor either.  When I boot my old 2.6.36 vanilla kernel
everything works as expected. I have lots of lines like these in the kernel log
file when using 2.6.37:

[drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 96

I have tried the patch from comment #6 to no avail. The monitor stayed turned

It would be nice If I could update to a newer kernel version soon.
