=46irst You should try manualy all 6 variants of starting order.
startx -- -layout X2 vt17
then from xterm start secondary X server and so on.
Also for proper Nvidia initialisation mostly works
X -layout noprefbusid -probeonly
where "noprefbusid" is standard xf86 layout without limitations like
prefbusid. After "probeonly" nvidia kernel module is initalised correct and
user can start/stop xf86 any times.

Who knows how compatible is this set of video adapters. Also You have 3 pai=
rs
for tests.

Patched xf86 does not need for hackvideo. Someone may have unpatched xf86
and will test linux-ruby anyway :) Sometime videoapdapters like prefbusid,
sometime hackvideo. We do not have report statistic.
Patched xf86 does not need for Option        "PciOsConfig" "1"
