I finally got a 10G card that is recognized by FreeBSD (9.1-stable):
...
ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.4.8> port 
0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 
0.0 on pci4
ix0: Using MSIX interrupts with 9 vectors
ix0: RX Descriptors exceed system mbuf max, using default instead!
ix0: Ethernet address: 90:e2:ba:29:c0:54
ix0: PCI Express Bus: Speed 5.0Gb/s Width x8
...
but it apperas as ix0/ix1, manuals only mention ixgb/e,
and ifconfig:

ix0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=401bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCS
UM,TSO4,VLAN_HWTSO>
        ether 90:e2:ba:29:c0:54
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: no carrier
ix1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=401bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCS
UM,TSO4,VLAN_HWTSO>
        ether 90:e2:ba:29:c0:55
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: no carrier

and pciconf:
ix0@pci0:4:0:0: class=0x020000 card=0x7a118086 chip=0x10fb8086 rev=0x01 
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82599EB 10-Gigabit SFI/SFP+ Network Connection'
    class      = network
    subclass   = ethernet

Secondly how is this fixable:
	RX Descriptors exceed system mbuf max, using default instead!

thanks,
	danny
