You need to look for information that can lead to driver development,
eg. in the h2200 there was:
- a Zeevo bluetooth module (TC2001?)
- a MediaQ graphics driver (MQ1178)
- the CPU (of course!) PXA255
- DRAM modules (2 of) (for 64MB that means 2 x 256Mbit chips)
- an ASIC (a companion chip for the CPU)
    the h2200 has a Samsung HAMCOP, while the h55xx(?) has a SAMCOP.
other chips that you can identify are a bonus at this stage.

Please dont break anything! :)) Ask Dr Jamey first :)
