pci-e config register modification in grub

Further discussion is in relation to MS stuff. 1/ ability to modify PCI Bridge Configuration Registers for DIY ViDock project http://forum.notebookreview.com/showthread.php?p=5324240 to allow the video card to work [ current workaround is boot DOS, use pcitool to do the mod, then use grub4dos to chainload the OS ] 2/ ability to restore a mini pci-e port's Extended PCI Configuration registers config to reverse HP bios whitelisting of wifi cards (See bottom of HP Mini pci-e wifi bios thread http://www.wimsbios.com/phpBB2/topic9388-105.html. No current tool can do this that I've found, with the DOS pcitool extending only to the 00-FF pci-e configuration registers, not the extended registers. 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 I'm running Ubuntu 9.04 with grub as the bootloader.
