Apologies, my troubleshooting was faulty.  In my testing when I was
switching between 2.6.29 / 2.6.34 there was a .config change that I
failed to notice.  In my  2.6.29 config I had all the default
config_pm and acpi options enabled, whereas in the later config I had
them all disabled.

So, the minimum acpi stuff needed for the driver to function is
CONFIG_PM and CONFIG_ACPI.  None of the timer stuff or anything else
appears to be necessary.  If that's the case (others can correct me if
not...) could we patch the Kconfig to look like this:

config VIA_VELOCITY
        tristate "VIA Velocity support"
        depends on PCI && PM && ACPI

since today it's only depending on pci.

If this is the right thing to do I can submit a patch .  Apologies
again for the red herring.  :-)

Cheers,
