[lug] Dual Graphic Card Boot Problem

[rm at fabula.de]

Hello list,

i just found the time to stick a second graphic card (ATI)
into my PowerPC so that i can reuse my old Radius Pivot
fullpage monitor as a second display. Unfortunately linux
decides to choose the Pivot monitor as the place to send
the boot messages -- which doesn't work since the monitor 
doesn't support any of the standard video modes (i intend
to use it only under X).
Is there a way to tell the kernel what graphic card/monitor to
use during bootup? (the main card is an ATI Radeon in the 
AGP slot, so they _should_ be distinguishable by their PCI
bus ID).

TIA 

  Ralf Mattes
