not u_long. On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().

hardware accelerated OpenGL. The hardware will still be reported during
boot using the nomatch system.

attaching to the device via chip*, use the newbus nomatch method to report
the device. This leaves them unattached so that a driver can be easily
loaded to grab them later.
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

pci_probe_nomatch, so it won't be in the way when loading USB as a module.
The reason for them being there in the first place is that every
motherboard comes with USB kit and this way it looks more pretty (peter).
The real solution will be to define some method of detaching a driver
after it has attached.
* Change the hack used on the alpha for mapping devices into DENSE or
BWX memory spaces to a simpler one. Its still a hack and should be
a seperate api to explicitly map the resource.
* Add $FreeBSD$ as necessary.
The old algorithm was:
if class == storage and subclass != SCSI device must be IDE
This results in claiming 'raid' and 'other' storage devices as IDE,
which is typically not the case.

IDE controllers if there isn't another PCI-aware ide or ata driver to
grab them. I've exported the match function since it could be used from
the ata-all.c code replacing ata_pcimatch() - but I have not touched the
ata code. I'd like to catch a few more devices this way, including USB
and other bridges etc.
