Hi,
Sure, I've uploaded my changes to github:
https://github.com/irush-cs/grub/tree/irush/testpci
Generally, this is a 'testpci' command that accepts one or more PCI device
IDs in the form "xxxx:yyyy" as arguments, or reads lines from a file given
by the --file parameter, and returns true if one or more of those PCI
devices is present, and false otherwise.
Thanks,
Yair.
