A while back I tried to use a ZDVD PCMCIA card in my laptop and it didnt work at all. At the time, I was told that the problem was that it used a weird memory mode. Just recently I found out that the kernel now seems to support that video mode (I assume it is MTRR) and that people are beginning to play DVDs with linux.
I was wondering if anyone was working on a driver for this card? I havent a clue how to write one, but perhaps it wouldnt be too hard now that the kernel supports the memory mode.
