Keep in mind that setting nvidiafb to totally ignore the EDID (either by not compiling in EDID support or by using e.g. the ignoreedid patch I had proposed) the snow effect is extremely reduced,I did not know that, just scanned the entire thread. Try this patch, it makes use of fb_ddc_read*() which I believe has extra steps to prevent display corruption. It also incorporates Luca's i2c fix.Applied. No noticeable difference, in the sense that the EDID debug output is still the same and so is the snow effect.
Here's a temporary workaround: In drivers/video/nvidia/nv_i2c.c:nvidia_probe_i2c_connector(),comment this out: if (par->chan[conn - 1].par) edid = fb_ddc_read(&par->chan[conn - 1].adapter); and make sure CONFIG_FIRMWARE_EDID=y.
