EndSection

i.e xorg is configured to use 2:4:0, after insmod drm.ko debug=1, the drm
appears to enable interrupts from both cards (will attache syslog) however only
works with the first card it sees.

Resulting in repeatable failures on method 0x03b0 as nv05 0028 doesnt
understand method 0x03b0 (does not appear in a clean renouveau output for
10de0028).
