The Matrox Meteor II consists of the custom Matrox VIA (Video Interface ASIC) which connects to the PCI bus.
There are different models:
Matrox Meteor-II (aka Matrox Meteor II/Standard) Part Numbers: METEOR2/4 : PCI MET2-C/4 : CompactPCI MET2+/4 : PC/104-Plus Matrox Meteor-II/1394, Part Number: METEOR2-1394 Matrox Meteor-II/MC (aka Matrox Meteor-II/Multi Channel) Part Numbers: METEOR2-MC/4C : PCI MET2-C-MC : CompactPCI MET2-MC+/4 : PC/104-Plu Matrox Meteor-II/DIG (aka Matrox Meteor-II/Digital) Part Numbers METEOR2-DIG/4/R : PCI, RS-422 digital (METEOR2DIG64R ?) METEOR2-DIG/4/L : PCI, LVDS digital MET2-DIG+/R : PC/104-Plus, RS-422 (METEOR2DIG64L ?) MET2-DIG+/L : PC/104-Plus, LVDS Matrox Meteor-II/CL (aka Matrox Meteor-II/Camera Link), Part Number METEOR2-CL/32
Note 1: The Meteor II is the successor of the Meteor, Meteor/RGB, Meteor/PPB, and Meteor/RGB/PPB boards. Matrox Meteor comes in four versions: Matrox Meteor, a standard monochrome and color frame grabber. Matrox Meteor/PPB, a standard monochrome and color frame grabber with an integrated PCI-to-PCI bridge. Matrox Meteor/RGB, an RGB color frame grabber. Matrox Meteor/PPB/RGB, an RGB color frame grabber with an integrated PCI-to-PCI bridge. The "PPB" boards were introduced to address compatibility problems with chipsets on early Pentium PRO motherboards.
Note 2: There is also a card called Meteor-II/Display, but this is not a framgrabber !!! MET2-C-DISP/AD Graphics adapter for CompactPCI with one analog VGA and one digital VGA (DVI) output MET2-C-DISP/A24 Graphics adapter for CompactPCI with two analog VGA outputs MET2-C-DISP/D24 Graphics adapter for CompactPCI with two digital VGA (DVI) outputs

User experience
I have what I think is a Matrox Meteor II Multichannel card. I have had no luck getting it to work with v4l2, but here's how far I have gotten, in case it helps anyone out.
lspci gives:
... 0000:03:01.0 ff00: Matrox Graphics, Inc. VIA Framegrabber ...
lspci -n gives:
... 0000:03:01.0 ff00: 102b:4536 ...
In order from **oldest** to **newest** here are relevant driver projects that I found. None have been updated in the last year.
- K-Team driver project (2002)
- Emlix driver project (2003)
- Marcus Furlong's Sourceforge driver project (2005)
The best I was able to do (as of Apr 26 2006) was:
(1) Download the latest version from the Sourceforge project CVS:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/meteor2mc login cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/meteor2mc co meteor2mc
(2) Made some changes. My changes are contained in the following patch, produced by diff -u:

Basically, I made everything non-inline (there were recursive inline problems), changed io_remap_page_range to remap_pfn_range, changed card->pdev->slot_name to card->pdev->dev.bus_id, and modified the Makefile. Maybe I did something else too, I don't remember.
(3) Compiled on Debian with kernel linux-image-2.6.16-1-686 (and the matching kernel-headers package installed), and gcc-4.0.
(4) Tried "modprobe meteor2mc" which succeeded and left the following messages in dmsg:
meteor2mc: Unknown symbol io_remap_page_range meteor2mc [via_module_init]: loading driver (dmask: 0x0, himem_offset 0, max_himem_mb: 16) videodev: "meteor2mc (#0)" has no release callback.

(5) So far so good. But v4l2ucp fails with "/dev/video0 is not a V4L2 device". So it's not quite working yet.
xawtv fails with
/dev/video0 [v4l]: ioctl VIDIOCGCAP: Invalid argument no video grabber device available
Please be aware that I am not a kernel guy and just hacked my way through this; I had no idea what I was doing, so it's possible that some of my patches weren't right.
