Ah. I think I know what this *may* be. It looks like the kernel you have there does not have the correct memory mappings for the issue 9 rio player (ie, 16MB in one bank - the issue 7 has 12MB in 3 banks of 4MB).

The v1.02 kernel had this support added (vs the v1.01 which didn't have it). Is someone building kernels from old source?
