Yes it would work, there is a problem with the approach taken by fbdev/glint, the BusID info isn't used at all there for the choise of the device to be opened, without the fbdev option you always get /dev/fb0 which might not be what you want.According to the XFree 4 documentation, the BusID determines the device, and thus the framebuffer used, even in the case of fbdev. So I'm kinda confused.
This doesn't apply to framebuffer devices, I guess it's about the PCI devices. There's currently no safe way to find the corresponding fbdev for a given PCI device and vice versa. But it's being worked on.

Here is a small patch (untested) that changes r128 to use the "fbdev" option instead of using BusID to get the fbdev device. If the BusID and fbdev options don't match bad things will happen so be carefull there. For people that don't have more than one r128 card the previous behaviour works better so don't use it...If I apply your patch and recompile, how should I modify the config file? Get rid of all BusID's? Just for the second monitor?
I suggest always giving all BusIDs, it doesn't hurt as long as BusID and fbdev match. Michel ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
