Hi folks,
I have had a problem with VIA chipsets. I abused GRUB to solve it. The
intermediate product is a PCI config space patcher in GRUB. Not that
it's anything new, as GRUB already contains proper PCI in
netboot. However, I added a command line interface so it's available at
boot.

I haven't spend much time beautifying this patch, simply because I want
to get your oppinions first, so I won't waste my time.
The patch also permanently enables NETBOOT_SUPPORT, because the PCI code
is part of netboot.
Also I kicked the optimization in cmdline.c to rely on lexical ordering
of the command names. That's seems smart, but isn't. I spend almost 60
minutes figuring out why the command I added at the end of the
builtin_table doesn't show up at boot. So, you see the optimization
isn't worth the hassle. It's not like we have a million command names to
search through.
