Heh the counter issue is what led to this patch.  I think the
UDP counters should be fixed already.  Please have a look at
net-2.6.25 and let us know if it's still broken.

As to the SNMP counter issue in general, Christoph Lameter's
new percpu code will greatly simplify this and we won't need
to disable preemption or do the fancy softirq/user splitting
that we have right now.  I eagerly await its acceptance into
the Linux kernel.

Cheers,
