We've been using IBM x306s for some time now (and previously x305s) with
1.6.2 (with a tiny pciide.c hack to get DMA working). The Ethernet isn't
supported with 1.6.2, but is in 2.0. Here's a 1.6.2 dmesg, I'm getting
one of these servers in next week, so I'll stick 2.0 on it.

N.B. The new x336s are NOT well-supported (Ethernet chipset is not
supported in 2.0 and I recall seeing issues with S-ATA too).
