2.6.11 Problem with latest mga_vid

[Todor Dobrikov]

Hello,
I' managed to compile the module and to insert it in the kernel but
after that when I run mga_vid_test it says that the driver is not loaded.
dmes:
Matrox MGA G200/G400/G450/G550 YUV Video interface v2.01 (c) Aaron
Holtzman & A'rpi
mga_vid: Found MGA G550 at 0000:02:00.0 [0000:02:00.0]
mga_vid: MMIO at 0xe28d8000 framebuffer: 0xE2000000
mga_vid: OPTION word: 0x400A1520 mem: 0x05 SDRAM
mga_vid: detected RAMSIZE is 32 MB
mga_vid: 1 supported cards found
mga_vid: using major: 83 (assigned or default!)

This is because I do not have /dev/mga_vid. I am using *pure* udev on
2.6.11 and probably this is causing the problem. I saw that there is
*partial* support for udev. What should I do to bring it up?
Thanks in advance,
Regards,
Todor

How about creating the required device node?

`mknod /dev/mga_vid c 83 0`, as it's documented in the mga_vid.c source.

I.e. do by hand what udev does for you. Either that, or wait for us to
finish up udev support.

Side note: I got a patch for udev support, i will have a look at
it after my exams and if it's ok, i'll make a new snapshot.
