Here you are:

Remember I'm using nvidiafb as a module, it's not compiled in. So what
I do is
modprobe nvidiafb
Is there a way to specifiy resolution when loading nvidiafb this way?
Presently, when compiling without DDC support, I get this:

but a borked screen (see further down)
BTW, I think that having it in module form may be part of the problem:
even the old rivafb acted differently when in module form (as I
mentioned in my original post)
BTW #2: There are two interesting differences between the
(modularized) nvidiafb in Debian and the one from my kernel:
1. Debian's nvidiafb resets the console font to 200x75 on load, while
the one from my kernel doesn't
2. If I try to change resolution or color depth when using my kernel,
the screen gets garbled, and there is no way to restore it.

I'm afraid this will have to wait.
And while we're talking about Dell: my configuration (GeForce2 Go on
Dell Inspiron 8200 with UXGA monitor 15" at 1600x1200) is known to be
borky even with nVidia's own driver for Windows XP --not all versions
work correctly.
