Do you still get link beat detection when the phy is powered down?

No.
As for link detection on the switch connected to this card:
If I have WoL turned off, then I don't get link beat detection.
If I have WoL turned on, then PHY won't be powered down, and I get
link detection on the switch.

does that matter?
If the interface is down, nic drivers aren't expected to detect
link... if userspace wants to find link status it should have the
interface up.

I don't get link beat detection with the original driver either, when
interface is down
(unless I pass it -a, but then it will bring the interface up).
