Hmm, once the via driver gets loaded it shares IRQ 9 with acpi and that
makes the via_rhine driver on IRQ 11 crash. That kind of thing can be
difficult to fix. Did your Sid upgrade involve a new kernel? If so then
it might be the simplest thing to go back to the old kernel or to make
do without acpi for now. Otherwise you might have to be prepared to read
the documentation and changelogs of all involved kernel modules and hope
that somewhere there is a module option which fixes this. Since I don't
have this hardware I cannot say anything more.

This may be related to disabling acpi. Did you check if someone has
posted something about this model on tuxmobil.org?
