I don't remember the exact details, but we determined that the 2.0.x kernel was trashing some data structure during initialization if there was too much memory. It seems to work correctly with mem=960M; we actually patched our kernels to use that as an upper bound on the amount of memory to use, regardless of what the BIOS or user say about how much memory is available.
