 Hi, Tom,

 Thank you for the great detective work!  Official guidance from AMD is for
 OLPC to use the GX500 instead of the GX533, so the proper SKU is the
 366/244 spec, and all DRAMs will be chosen to support CL2 by design.  As I
 mentioned previously, the Infineon RAMs were actually a manufacturing
 error, not a variant design.

 Thanks again!
