Yep, same here on Sidux, I tried the latest Sidux last week in hopes
it would be "fixed".

I believe the problem is rooted in Debian "Lenny". It's the Debian
"Sid" and "Lenny" code that is evidently having problems (MEPIS 8,
Debian 5 and newest Sidux all having problems) I suspect if you try
the new Debian 5 "Lenny" that you'll also have problems on your
hardware, as I have.
