Yes, you are right ! In my /etc/modules is the entry "ide-generic" and not the 
via82cxxx. This one is beeing loaded by the kernel later. I will fix it.

Maybe you are right, the ide-generic first loaded could disturb the 
via82cxxx-module.

Good idea !

I will test it. Here is my /etc/modules 

ide-cd
ide-disk
ide-generic
r8169
psmouse
freq_table
powernow-k8
cpufreq_userspace
ide-scsi
nvidia
v4l2-common
usbnet
irport
usb-storage
firmware_class
cpufreq_ondemand
cpufreq_conservative

Maybe this helps.
