I must have gone too fast and missed something.
I have tested several installations of debian testing :

1. From an amd64 debian testing netinst CD :
    Which meens a full 64bits system => kernel and packages.
    Then, I upgraded to a 2.6.26-rc8-amd64 kernel and experienced some freezing issues

2. From a 386 debian testing netinst CD :
    I installed the base system which is shipped with a 2.6.24-486 kernel. (needed noapic, nolapic and irqpoll options)
    Then, I upgraded to a 2.6.26-rc8-amd64 kernel.
    So only the kernel space is in 64bits ? am I wrong on this point ?
(I'm really not sure here :(, my understanding of 64bits systems on linux is very limited)

    I let my laptop on all the night and it was still running this morning...

you probably have not blacklisted snd-pcsp nor are you using latest
alsa userspace from unstable, which would do that for you.

I used the latest alsa userspace from unstable (alsa-base, etc. packages) and blacklisted the snd-pcsp and still no result.
The soundcard is detected and alsa software works fine : alsamixer, alsactl...
But no sound :(


Last problem with ATI fglrx drivers :
They don't compile on a 2.6.26 kernel on amd64.

this model is worked on, ath5k is pretty young
