problems with davicom dm9102a

Hi all,

I've just installed FreeBSD on my new hardware and there seem to be big 
problems with the integrated network interfaces.

The major facts:

- FreeBSD 5.2.1-RC2
- i386
- PCI Davicom 9102A
- dc (DEC Tulip) driver
- "no carrier" although the connection is ok
- "failed to force tx and rx to idle state" when trying to get an IP by 
DHCP, trying to determine the media type manually etc.
- the MAC address  seems to be correct (have read about people who had 
the problem that the MAC was 00:00:00:00:00:00)
- most recent version of if_dc.c

Any suggestions?

Thanks for your help.
