Dell 1900FP -- Solved!

I figured out how to get the native 1280x1024 resolution working with this LCD monitor. The trick is to use

fb1280x1024 xmodule=nv screen=1280x1024

[I have an NVidia card, but I guess that's not the issue really) at the boot prompt. If you use "knoppix" instead of "fb1280x1024", when Xfree uses DDC to autodetect the maximum available resolution, it fails to report 1280x1024 because the current (default) text / fb mode used during the boot process, etc., is 1024x768. So, forcing 1280x1024 at the boot prompt fixes the problem.

"viro" suggested using knoppix-txt, probably for the same reason. This did not work for me, but it may work for other users.

OK I was fighting with this same issue...

I wound up using:

fb1280x1024 vsync=60 xmodule=nv
That boots with nv(fbdev) at 1280x1024. If you omit the xmodule it will boot using Xfree86(fbdev). Specifying the screen seems to be unnecessary, but...
w/ Knoppix 3.3_2003-09-24 you need to put a couple of spaces at the end of the line since it 'eats' the last char or 2. I originally had the vsync=60 at the end and noticed it was trying to use 6Hz!
