happens if you have a BIOS with a 'Plug & Play OS' setting and you leave
it set to 'Yes.' This is wrong for FreeBSD (and LoseNT): it should be set
to 'No.' Apparently it's still possible to map the iobase of the NIC and
have the card work by reading the config space manually (which is what
the driver does if pci_map_port() fails) but we need to warn the user to
do fix their machine anyway. Anyway, warn the user to check the 'Plug &
Play OS' setting in their BIOS if mapping the io space fails.
The driver now identifies the IBM PCI-PCI Bridge fitted to newer
Matrox cards and initialises it.

via an IBM PCI-PCI bridge (82351 or 82352 or 82353)
The driver must identify if it is on a secondary PCI bus, which is
created via the IBM PCI-PCI bridge. If it is, then it must initialise
the IBM PCI-PCI bridge correctly.
To do this, the following new functions are added.
Because they use the pcici_t tag, they are considered 2.2 compatibility APIs
pcici_t * pci_get_parent_from_tag(pcici_t tag);
int pci_get_bus_from_tag(pcici_t tag);
(The _from_tag suffix is used to prevent clashes with similarly named
newbus PCI API functions)

The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it. cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used
bogusly. Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.
Move bdevsw() and devsw() functions to kern/kern_conf.c
Bump __FreeBSD_version to 400006
This commit removes:
72 bogus makedev() calls
26 bogus SYSINIT functions
if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

chipset. First you thrilled to the 3c905, then you trembled at the
3c905B, now gaze in wonder at: the 3c905C! This appears to be another
3c90X series chip called the Tornado (PCI ID 0x10B7/0x9200) and should
be equivalent (from the driver API perspective) to the 3c905B, so all
we have to do is add the PCI ID to the list.
Reformat and initialize correctly all "struct cdevsw".
Initialize the d_maj and d_bmaj fields.
The d_reset field was not removed, although it is never used.
I used a program to do most of this, so all the files now use the
same consistent format. Please keep it that way.

use ALPHA_PHYS_TO_K0SEG(offset) rather than just plain offet. I've verified
that this does not break other platforms (I've tested an AlphaStation 200
and a Personal Workstation 500au with this patch).
As to why this works, well.. Its black magic as far as I know. I obtained
this hack from Myricom, who in turn, obtained it from Compaq engineers.
Without this hack, XFree86 cannot talk to a PCI graphics card.
