I'm contemplating putting together a system based on
http://www.supermicro.com/products/motherboard/P4/E7221/P8SCi.cfm .  I'm
wondering about support for the BCM5721 GigE and Intel ICH6R SATA
controllers.

I see that if_bge nominally supports the Ethernet card, but there are
warnings in the driver that seem to imply that it might not really work
well.

I don't know about the SATA controller; I do know that it works on
FreeBSD.  I don't need the hardware RAID support.

Ideally, this machine would run 3.1; more likely, it would run some
snapshot of -current for the better Xen support.
