Patch: Better PCI network device detection

[Frank Mehnert]

Hi,

appended is a GRUB patch that resolves two drawbacks in the current
GNU GRUB cvs release:

- PCI ethernet cards will be testet first. If a known PCI device was
  found, the belonging probe function is called _immediatly_!

- The number of the PCI bus the device resides on is passed to
  the probe function too. Some cards have to do PCI config register
  manipulations and therefore has to know the PCI bus number.
  This affects nearly all PCI ethernet cards.

I hope that you incorporate this patch. 
I've already signed an GNU assignment.
