--- Comment #23 from Maik Freudenberg <hhfeuer at gmx.de> ---
@Daniel Drake: that's coherent with my investigations, even on a 740M without
any outputs setting the bit at 0x488 changes the pci header type to 0x80,
multifunction. My idea would be to use the pci_scan_single_device function to
add the sub-function device. The really old fakephp driver available in kernels
<2.29 would have been useful for general testing, but that's gone AWOL. The
later one is useless, tested it. I also want to use the holyday break to do
some development on this. What have you been thinking about?
