Yes, I saw that in my 750UM too. But it has nothing to do with cpu speed, so
you would have to create a new sysctl for it.

This kind of powersaving also needs no port-specific support (like gpios),
so I would make the new sysctl in sys/arch/powerpc/oea.

Got a D-Link DFE-670TXD from a friend and it's the same. The card it only
recognized when inserted before booting the kernel and it won't cause any
interrupts.

I can see the network status change (active or no carrier), but this doesn't
need an interrupt AFAIK. When trying to use the interface I get:

ne0: device timeout

So it's definitely a "no interrupts" problem. :|

Ok. My current should be recent enough.

The the stride is wrong. But why? And how can I find the right stride?

It's a Radeon Mobility 9600/9700. Probably RV360?

No, but I tried that now - without success.
I anybody else running current-X11 on macppc?
