http://xpenology.me/compatible/ seems to be as close as you can get for now, but it is hardly a wiki and no real "notes" alongside the h/w list that I can see?
Also that site is not always online for me...
My main hardware issue is that the Realtek 8111 (8168D) NIC is being overridden by the 8169 driver in DSM 5.2 builds, so WOL does not work,
even though it works perfectly for windows on the same box.
Basic 8168 network comms are ok, so I am tolerating it by putting box within easy reach for manual poweron.
No documented tweaks for xpenology work to bring it back to the 8168 driver (e.g. rmmod, insmod in xpenoboot syslinux.cfg),
and no DSM kernel build support so we could replace the underlying r8168.ko driver ourselves...
That xpenology.me site's listing of 8168 compatibility as YES gives me little confidence in referring to it for any replacement PCI/PCIE adapter...
I confirmed that ESXi 5.1 supports WOL for 8168D (ESXi 5.5, 6.0 remove that by default)
however ESXi also has no easy way to then put the xpenoboot vmdk on a usb flashdrive to avoid wasting limited sata ports, and then it looks like existing DSM drives would need to be wiped as new vSphere datastores.
Perhaps better to wait for DSM 6.0 with 64bit support and new drivers to see if 8168D WOL works on it... for which we will still appreciate a hardware compatibility wiki
Update - got WOL working intermittently if I script-force the following:
ethtool -s eth0 wol g
however it is working more reliably on a RTL8168D NIC on ga-890gpa-ud3h v2.1 mobo, than on a RTL8168E NIC on ga-890gpa-ud3h v3.1 mobo
