Comment:

 Replying to [comment:26 tsylla]:
 > The worst part about this is that GX cannot run at CAS3. That setting
 does not exist in GX's registers. This means there is no "safe" way to run
 the infineon devices. You can run CAS2.5, and it will probably be pretty
 good, but it still really isn't meeting the Infineon datasheet spec. The
 olpc higher-ups will have to decide the correct path to address this.

 Very early on, C.H. Yang had mentioned that the OLPC RAM was designed as
 CL2.5 (IIRC, in response to Ron and Ollie's questions).  I will check the
 Infineon datasheet more closely, and will verify whether the timings are
 in fact valid when run at CL2.5 timings.
