I FOUND IT! I risked getting the arrows in my .....
The
Sonnet Tempo SATA Pro ExpressCard | 34 WORKS! in an HP Probook 4530s! It has two eSata ports!
<----- See my profile for the Probook model details.
It's a 3Gbs card promising 125MBs. I saw 95MBs writing 400GB from the internal SATA drive, while reading from a USB 2.0 drive peaked at 35MBs.
Caveats: You MUST install the Sonnet driver. Choose the one for Macbook Pros.

The card has two eSATA ports so it sticks up from where the ExpressCard slot is, enough to cover the HDMI and left rear USB 3.0 port. There's enough of a gap that my tiny Logitech universal USB dongle still fits.
I got this Cable Matters 15 foot right angle HDMI cable from Amazon.
http://www.amazon.com/gp/product/B004D5GXQI/ref=oh_details_o00_s00_i00 and trimmed the right side of the back of the right angle plug with a utility knife to make a divot about 3/8" wide and 1/8" deep to get the card to fit snugly over it. I wouldn't go any deeper because I hit the hint of some metal or wiring.
I would recommend shutting down the Mac entirely while you tinker and plug in eSata cables. ExpressCards in general will pop out if you breathe on them and no matter how hot-swappable they're supposed to be, I wouldn't push it, especially when you have hard drives attached that might get corrupted. Disks are not hot swappable unless you unmount then cleanly. This card seats pretty securely but the card will usually pop out when you press to connect the eSata cables.
My Probook 4530s Hackintosh did the usual where it takes two powerdown reboots to be happy. I got the circle/line icon on the Apple on the first reboot. You might want to boot first with the card with the driver installed and power down and attached the eSata drives and power up. That way the Mac is seeing only one new piece of hardware at a time.
The card goes for $44.95 at OWC.

I got mine from jayhawksales on eBay for $40 + $4 shipping. He has only one left as I write this.

Of course, I'd like even more speed. Sonnet has a 6Gbs version, but it goes for $140. This is plenty of speed for my laptop.
I'll post some pictures soon.
