5.2-RC oerrs and collisions on dc0

Hello,

I tried 5.2-RC2 on alpha and netstat -i keeps showing oerrs and collisions on 
dc card (DEC DE500-BA):

I also tried nge card and it works fine. The 21143 works without errors on 
5.1-RELEASE.
This has been reported by Andy Farkas here:
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=2200233+0+archive/2003/freebsd-current/20031116.freebsd-current

Furthermore I tried different snapshots from current and it goes thusly:
cvsup with 2003.07.07.00.00.00 shows errors and collisions, but if I 
revert /src/sys/pci/if_dc.c from 1.115 to 1.114 and /src/sys/pci/if_dcreg.h 
from 1.34 to 1.33 the errors are gone.

Attached are dmesg and pciconf -lv output from 52RC. I can play with this box 
for the holidays so mail me if there's anything I can do to help solve this.
