Boot options for radeonfb?

Greetings!

I have just recently begun to try out radeonfb. I have it compiled into my 
2.6.9-rc3 kernel (I need some of the usb improvements, hence rc3).

It works great with my laptop and lcd screen, but I can't get it to adjust 
itself for when I have my CRT plugged in. I can't find any docs under 
Documentation/fb/ for this particular driver.

Laptop: Dell Inspiron 8600
ATI card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
LCD: I can't find the brand, but it's 16:10 aspect with default 1680x1050 
CRT: Dell P1130 1280x1024@75 max

I have tried to pass parameters at boot through lilo. I do get display on 
the CRT, but it is unuseable.

append="video=radeon:"
It detects my LCD settings and applies them to my CRT display. I only get 
the 'middle' difference between 1680 and 1280 on the horizontal.

append="video=radeon:1280x1050-24@75,crt"
I get fonts so large I can read them across the room... what is displayed 
to the CRT, anyway. Everything is cut off both ends.

append="video=radeon:1280x1050-24@75"
It just completely ignores this and goes with the default 1680x1050-8@60

It is seeing the CRT connection, but seemingly making no adjustments for 
it, and the above commands were guesses on my part, due to lack of 
documentation as to driver options.

So... any clues? Please?
