nForce4-SLI, PCIe, ATI X600 supported by FreeBSD 5.3?

[O. Hartmann]

Hello.
I would like to know whether this hardware combination is supported by 
FreeBSD 5.3-STABLE:

Mainboard: ASUS A8N-SLI or GigaByte K8NXP-SLI with ATHLON 64/Winchester 
(2.0Ghz)
SATA harddrive
ATI Radeon X600/Pro based PCIe(!) graphics board

Especially the GBit NIC should be supported (
# Marvell 8053 Gigabit Ethernet controller
# CICADA8201 Gigabit LAN PHY chip)
