12/08/04 version of Nvidia driver from Mark Vojkovich, including these
fixes since last sync: Fix some DAC/Graphics memory contention issues
on newer NVIDIA chips (specifically, NV40). More PCI IDs. Also, I've
had trouble getting some panels to work automagically so I expose an
FPTweak option to let the user adjust a troublesome register.

sync with XFree86, including: Support for new NVIDIA chips. Egbert has
a laptop that needs some DPMS ordering reversed. New chip support and
workaround for Toshiba M30 laptop issue. PCI-Xpress chip support. DPMS
support for DVI. Cursor changes for NV11 so that alpha blended cursors
will work in conjunction with dithering (laptop panels). It previously
did not. HW support for alpha blended stretch blits on NV5 and higher,
though nothing is using them at this point. Add support for VBlank
syncing the Xv Blit adaptor on hardware that supports it (NV11 and
higher). Make console restoration a little more robust. We were making
an assumption that failed on a newer laptop. Workaround for some NV31
DVI artifacts.
Also add nVidia license statement to nv man page to comply with requirement
that it appear in "user documentation"

Added support for IBM space saver keyboard (Stefan Dirsch). Added support
for Cherry CyMotion Master XPress (Marcus Schaefer).
Change order of SetDisplayDevice(), HWRestore(), UnbindGART() and
RestoreBIOSMemSize() to be exactly opposite to the Save procedure in
EnterVT() (Matthias Hopf, Alan Hourihane).
Fix text mode restauration by removing the assumption that the register
which determines which head is programmed is set. to the active head by
the BIOS (Mark Vojkovich).
When I wrote the resource code 5 years ago I made some assumptions which
turned out to be false: I've assumed that the bus number of the PCI
hostbridge would be the PCI bus the bridge links to. This is not
correct. Fixing this assumption is not easy. However I hope that the
attached patch will make the system work regardless as it 'ignores'
host bridges from which the target bus is not known. This should not
matter at all as we really don't care about host bridges (unless we
have bridge specific code which retrieves information about the
bridge).
Fixed server crash on reset when a structure allocated in PreInit() was
freed on CloseScreen().
Fixed ring buffer lock ups that happened because the structure that
contained ringbuffer data was not zeroed after allocation.
Fixed numerous warnings due to signed unsigned comparisons.
programs/Xserver/hw/xfree86/drivers/nv/nv_driver.c:
(NVBacklightEnable): Changed the order in which the sequencer registers
and the backlight control registers are written. The sequencer control
register need to be written first otherwise DPMS screen blanking
produces vertical bars on a mobile device. lib/Xau/Imakefile: Build
libXau static library PIC so it can be linked into toolkits that would
like to wrap its functionality.

Delete xf24_32bpp, as s3virge was the last user. Fix up some comments
to refer to fb rather than cfb.

list, so the loader knows not to complain about unresolved symbols when
an optional module isn't loaded. This typically manifests as warnings
about fbdevHW symbols when the user isn't using the framebuffer
console.

*Weak() resolver functions.

framebuffer formats except cfb and the overlay modes should work, and
r128 and radeon need to be loaded from the ati driver (both issues to
be fixed soon). Tested on i740, s3virge, mach64, tdfx, vesa, and vga
drivers. elfloader users shouldn't be affected.
