The XDR RAM configuration is sent to the Cell BE processor via syscon's packet during booting, however you can query it at any moment.
To fetch it you need to send a packet to the system controller with service id = 0x12 and payload consisting of two zero bytes, an answer have a size of 0x80 bytes.

Sample

Here is an example output from Slim console:
