receive errors and FIFO overflow with vr nic

I am experiencing a lot of messages like this

vr0: rx error (09): FIFO overflow
vr0: receive error (0407) overflow

when my system (VIA CN 10000) is under high network load (ftp, nfs, bacula).

tuxillo suggested to look into the recent changes FBSD did to the driver 
to get around these problems:

this is the hardware info about the card:
