LCD panel list (X200 panels listed there): http://www.thinkwiki.org/wiki/TFT_display
All LCD panels for the X200, X200S and X200 Tablet are known to work.
AFFS/IPS panels

Look at wikipedia for difference between TN and IPS panels. IPS have much better colour/contrast than a regular TN, and will typically have good viewing angles.
These seem to be from the X200 tablet. You need to find one without the glass touchscreen protection on it (might be able to remove it, though). It also must not have a digitizer on it (again, might be possible to just simply remove the digitizer).

BOE-Hydis HV121WX4-120, HV121WX4-110 or HV121WX4-100 - cheap-ish, might be hard to find

Samsung LTN121AP02-001 - common to find, cheap
If your X200 has an LED backlit panel in it, then you also need to get an inverter and harness cable that is compatible with the CCFL panels. To see which panel type you have, see #led_howtotell. If you need the inverter/cable, here are part numbers: 44C9909 for CCFL LVDS cable with bluetooth and camera connections, and 42W8009 or 42W8010 for the inverter.
There are glossy and matte versions of these. Matte means anti-glare, which is what you want (in this authors opinion).
Refer to the HMM (hardware maintenance manual) for how to replace the screen.

X200S
http://forum.thinkpads.com/viewtopic.php?p=618928#p618928 explains that the X200S screens/assemblies are thinner. You need to replace the whole lid with one from a normal X200/X201.
How to tell if it has an LED or CCFL?
Some X200s have a CCFL backlight and some have an LED backlight, in their LCD panel. This also means that the inverters will vary, so you must be careful if ever replacing either the panel and/or inverter. (a CCFL inverter is high-voltage and will destroy an LED backlit panel).
CCFLs contain mercury. An X200 with a CCFL backlight will (unless it has been changed to an LED, with the correct inverter. Check with your supplier!) say the following: "This product contains Lithium Ion Battery, Lithium Battery and a lamp which contains mercury; dispose according to local, state or federal laws" (one with an LED backlit panel will say something different).
Hardware register dumps
The coreboot wiki shows how to collect various logs useful in porting to new boards. Following are outputs from the X200:
