Subject: [PATCH] NeoMagic Framebuffer Driver

Hi,

attached is a new version of neofb for Linux 2.4 that
supports all PCI based NeoMagic chipsets. It has been
ported from the XFree Driver. Features include console
acceleration and LCD panel size detection. Basic features
like mode switching, virtual resolutions, mtrr and mmio
are also implemented.

I've seen this driver working on many notebooks now and
would like the driver to be included into the kernel
distribution.

Thanks.

Hi,

this version has a MODULE_LICENSE, applies fine to linux-2.4.18-pre6.

This seems to react rather badly when loaded from within X; I managed
to lock the machine trying to switch VCs after doing so (for example,
when I tried with matroxfb, it only screwed up the display.)

Yes, I know this falls into the 'don't *DO* that' category. :)

The Matrox graphics cards are quite resistant when being programmed
by two drivers simultaneously.

Definitely ;)

I'm quite happy since the latest 2.4.1* and X 4.1.0, switching between
console framebuffers and X with my MGA G450, it didn't result in a color
screw anymore, although it worked somehow before...

No, but if you did, your eyes bled category :)

A small glitch remains: 1 of 4 X(dm) (re)starts the screen is 3 cm
discentered. Switching back and forth fixes it always.
