My build in ethernet card (ASUS A8V mobo) does not work.
(I've tried HEAD, RELENG_5 and RELENG_5_3):

kc0: <Marvell Gigabit Ethernet> port 0xa000-0xa0ff mem
0xfbb00000-0xfbb03fff irq 17 at device 10.0 on pci 
skc0: Yukon Gigabit Ethernet 10/100/1000Base-T Adapter 
sk0: <Marvell Semiconductor, Inc. Yukon> on skc0 
sk0: Ethernet address: 00:11:2f:88:07:42 
skc0: no PHY found!
device_attach: sk0 attach returned 6

This is the device:

kc0@pci0:10:0: class=0x020000 card=0x811a1043 chip=0x432011ab rev=0x13 hdr=0x00
    vendor   = 'Marvell Semiconductor (Was: Galileo Technology Ltd)'
    device   = '88E8001 Gigabit 32-bit Ethernet Controller with Integrated PHY'
    class    = network
    subclass = ethernet

Are there any patches I could try out?
The only other NIC I've got is an Intel fxp that hard locks my system
after a while.
Thanks in advance.
