Problem with changes to vr driver

[walt]

I'm getting watchdog timeouts following yesterday's changes to
the vr driver.  The output from ifconfig and netstat -rn look
completely normal -- just no packets going anywhere.
The dmesg from the previous day's kernel:
vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0xec00-0xecff mem 0xe9041000-0xe90410ff irq 11 at device 18.0 on pci0
