Update... I had to mess with this more. I had a LiteOn LE-128M1S, Samsung PM800, and Samsung PB22-J SSD sitting around ... and a 44 pin to regular SATA bridge board (still JMicron 20330 based, but will work with "standard" SATA laptop drives).
Also, I was having a recurring problem of the Intel 1st gen 80 GB drive reverting to PIO mode (requiring a quick regedit delete of the master ide channel checksum entry) and I wanted to see if the Samsung drives exhibited the same issue.
1. The LiteOn drive did not work through the bridge. It did not work in my Mac Mini on native SATA either, but did work in a SATA FireWire enclosure I have. So I set that aside.
2. The Samsung drives both worked great. They support TRIM too, but I'm not running Vista, so the fact that both had garbage collection firmware was important. I had to wait a couple hours for GC to speed the drives up. Initial performance was miserable. It came right up after a couple hours letting the laptop sit idle tho. Worth noting that the Samsung drives can't hold a candle to the Intel one on 4k writes. Not even close. Still very fast compared to any magnetic disk. No issues with PIO mode or having to delete MasterIdDataCheckSum so far...
3. The standard SATA bridge board was significantly wider physically than the uSATA one, which made it tricker to install (can't remove the plastic cage, install the drive, then reinstall ... you have to "thread" the drive in through the standard "hole" with the laptop fully assembled. Hot glue the drive and bridge board together at the SATA connector so if you tug on the far end of the drive you get the bridge board also. The SATA connector has less friction than the PATA one, so if you don't do this and remove the drive, the bridge board will stay deep within your ThinkPad (and it's tough to get out, even with long nose pliers).
4. You can do this for under $73 bucks. The "full size sata" bridge board is $7.29 and Samsung 64 GB drives are $65 on ebay right now. This is a very very low price for some serious performance.
5. The disk activity LED works with the Samsung drive/bridge combo! It didn't work with my Intel drive/bridge combo. Nice to see the little guy blinking again, especially as the SSD itself is silent.
Pretty stout performance per dollar (note lower 4k numbers relative to Intel)

Hot glue the SATA connectors together (or you'll have a hell of a time digging the bridge board out of the 44 pin motherboard plug)
Tack the far end of the drive in place
Put a dab of hot glue from the top to the bottom of the case to reduce flex and ensure the drive is secure
Put the cover on and hit the road
