Are PCI configuration registers enough? If not can you research the
specifications?

I'm not familiar with pci-e and don't know how much additional code
would be required considering already existing pci code. Considering
windows share "chainloader" command with other OSes too one could add a
command "winfix" which will autodetect and do all the fixes necessary
for windows and then 30_os_prober.in can be modified to use this. This
way user doesn't need manual configuration. If autodetecting is too
cumbersome one could have separate commands in grub to do exactly the
fix you need. Could you make the patch and send it here. If you need to
import code from another project discuss it here first - not all code is
suitable for grub

For Linux I would recommend to contact developpers of corresponding
kernel subsystem - it will help them to improve driver. Further
discussion is in relation to MS stuff.
