Video/Audio on Dell Latitude LS :(

[xspager]

I just install Haiku on my laptop, an old Dell Latitude LS, it even works well, but i can see a black stripe on the screen, and when i play anything, this stripe get a lot of colors, each pixel one color :| that changes over the time, and only when playing a audio file. Note that when the workspace color appears on the screen i dont see the constant black stripe, it just shows later on boot process. Note too, that this machine works well on the FreeBSD, sound and video, but im not right about the sound on Linux(Ubuntu), the video behaves strangely sometimes, but is well most of time.

I belive that this problem is relative to the strange NeoMagic chips, in this machine they are, NM2200 [ MagicMedia 256AV Audio ], [ MagicGraph 256AV ] (Video).

When i play sound on my machine it make a strange noise on the speaker too, at the same time the strange thin black stripe gets a lot o colors on it`s pixels.

I had this problem some time ago when testing opensound on my Dell Latitude CPiA. From discussing with Francois this is an issue of the memory layout in this chipset. Opensound is not written with the Haiku Neomagic driver in mind.
