Dell Inspiron 6400 and FC5

Yep - it's officially simple. I now have sound, graphics and wireless all working.

1. Sound - cured by using Alsa drivers from at rpms
2. Graphics - you need the 915resolution hack
3. Wireless - newer FC5 kernel (2122); ieee80211 rpms and ipw3945 rpms
4. Lid fix - shutting the lid now no longer blanks the display permanently ;-)
   

You can get a lot more help from:

1. Malmot's blog (FC5)
2. Jacky Vuillemin (Mandriva 2006)
3. Graham Williams (Debian 3.1)
4. Jennifer Tsai (Ubuntu 5.10)
