Okay.  I don't actually have any of the system-on-chip (SoC) Marvell devices
like the one you are using there.  But they say that the SATA core on
the SoC is a Gen-IIe core, same as on the 7042 PCIe chipset.

So, I've plugged my UDMA-capable CF card into the CF-to-SATA adapter
and hotplugged that into a port on the 7042.

It works fine, reading/writing in UDMA mode 5.
Things also appear to be good with a Hitachi microdrive in PIO mode 3.

The CF-to-SATA adaptor I am using is this one:

Nice little device, compact, notebook compatible, and Fast!
