That should work provided you have a "1280x1024" mode defined and set  
the "fbdev" option to "/dev/fb1". But, I suppose you want fb0, right?

This thread should help:

That is correct, and the "1280x1024" corresponds to the resolution as  
specified in the PDC. IIRC, the A4070-* devices (HCRX family) only  
worked at this resolution, but might be switchable between 75hz VESA  
(separate H/V sync) and 72hz (sync-on-green). If your monitor is not  
receiving a sync signal use a serial console (power-on with the PS/2  
keyboard detached, 9600/8/n/1) and try the "co mo" command to view the  
video setting. "co mo list" should give you a list of options available  
for each of your two devices.

BTW, you might want to grab copies of the service manual & owner's  
guide for future reference:
