I've got an Asus P5LD2 Deluxe with a Marvell 88E8053 NIC onboard and it
works fine for me.  There is an issue if you're using the sky2 driver. 
What happens is under times of heavy network load, the driver will just
give up.  To recover, you have to unload and reload the module. 
Something else you can do is use the Marvell drivers.  I downloaded them
from the Marvell site and installed them as a kernel patch.  Recompiled
my kernel selecting their driver (sk98lin) and building as a module. 
I'm running kernel 2.6.22 on Gentoo.
