Some BIOSes (hi XGI!) will attempt to enumerate the PCI bus by asking
for the config space of every possible device number. This despite
perfectly functional BIOS methods to enumerate the bus exactly.
The address written to 0xcf8 contains the PCI slot address to send the
config cycle to. However, we would ignore that and always send the
cycle to the device whose BIOS we were running. This breaks some
integrated graphics platforms that have explicit knowledge about the
system's host bridge, for example.
The author of the int10 code looked at the VBIOS POSTing code
in DOSEMU to get some initial idea on how to POST a VBIOS.
To give credit to the DOSEMU Team for this inspiration a comment
was added to the code which could suggest that code from the
GPLed DOSEMU was directly incorporated into this code.
This patch should clearify the situation.
Print debug messages only when the appropriate debug bit is set in the
8086 state vector, so you can focus in on the call you're actually
interested in.
Convert all uses of PCITAG in int10 and vgaHW to 'struct pci_device'.
This allows the conversion of xf86ReadLegacyVideoBIOS and
xf86MapDomainMemory to 'struct pci_device' from PCITAG.

Re-removed most of the conflicting files.
tag bits when I originally coded it. I mistakenly thought that the
original code masked off the PCI function bits, so I just always
passed 0 as the function. That was a mistake.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
