I have a Dell Latitude CPi A366XT with a neomagic sound chip. Its detected fine but only boots 1 out of 6 tries, the rest hangs at the Hotplug script. After a bit of research i've found that the driver for neomagic is very buggy:

The only useful information on making it work was the last post on the link above:

Dell Latitude CPt 333GT with NM2360 chip, Neomagic 256ZX, works great

with ALSA 1.0.2 under SUSE 9.0. Did enable snd_viao hack and ac97 force options in Yast2 config of card. Have booted from cold boot with no problem.

Thank you!!

I have no idea what the snd_viao hack is or how to force ac97. Anyone with a neomagic sound chip have the same problem or know of a work around?

Ok I found out a lot of info on this issue here:

https://bugzilla.ubuntu.com/show_bug.cgi?id=7939

Basically its a known issue, the fix has been put into one of the hoary kernel updates but for some reason is not in the breezy kernel (which i'm running). There is a patch available to fix this but before trying that i'll try some of the workarounds mentioned. Anyone with a neomagic 256 sound chip should look into it.
