pre-nv50 KMS
...op via the VGA port and resolution is higher then 1028x1024, it
will say no signal. At lower resultion it shows distorted image. My
monitor native resolution is 1920x1080. You get some idea and know
what is going wrong. I did check the mode_state of ddx and kms, the
are almostly the same except the fb_start and cursor_offset are
different as expected.

[RFC, drm-misc-next v4 0/9] PCI/VGA: Allowing the user to select the primary video adapter at boot time
From: Sui Jingfeng <suijingfeng at loongson.cn>
On a machine with multiple GPUs, a Linux user has no control over which
one is primary at boot time. This series tries to solve above mentioned
problem by introduced the ->be_primary() function stub. The specific
device drivers can provide an implementation to hook up with this stub by
calling the vga_client_register() function.
