pci-e config register modification in grub

Hi everyone,

Wondering if grub2 can have an additional module added to do various pci-e Configuration Register fixups/modifications before launching into XP/Win7/Linux. Specifically I require:

1/ ability to modify PCI Bridge Configuration Registers for DIY ViDock project 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. 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 running Ubuntu 9.04 with grub as the bootloader. Can these features be added to grub via say the menu.lst file as well as some config file that can store the dump for (2) above??
