perhaps one of the following cheatcodes will help:

screen=1280x1024 Use specified Screen resolution for X
xvrefresh=60 or vsync=60 Use 60 Hz vertical refresh rate for X
xhrefresh=80 or hsync=80 Use 80 kHz horizontal refresh rate for X

example (type at boot prompt):
knoppix screen=1024x768 vsync=75

Attention: Use only refresh rates Your EIZO will survive.

I don't know a direct way to pass the monitor name to Knoppix.
