However, I'm still getting the same snowy effects, which doesn't come
as a surprise since the actual mode timings used are just the same ...

Yes, because the EDID has only 1 mode entry. But now you can use 'fbset
1024x768-60' (or any mode smaller than 1600x1200-60) for example and it
should work.

No, it doesn't. I've tried all the methods from 640x480 to 1600x1200,
and they /all/ come up snowy. This is starting to look queerer and
queerer. I've also tried changing vf min and max as you suggested:

Before we proceed, do you agree that the patch will allow you to change
video modes without disabling DDC support?  So this is still a valid
fix?

 You might want to change  vfmin and vfmax to 59 and 61

and even the M and MR methods which you suggested in the other email.
Since nvidiafb is being loaded from the command line because it's a
blacklisted module otherwise, I've been using the mode_option option.
However, neither the mode_option nor fbset seem to give me anything
not snowy.

When does your display become snowy? Is the snow constant or does it
only snow when doing heavy text operations, such as scrolling?

I presume that X's nv driver or vesafb does not exhibit this problem?
