Hi, I am somewhat of a hardware hacker.
Sounds like a chip initialization problem to me. I would probably save a *LOT* of effort for everyone if someone had/created a GOOD reverse compiler for MIPS and then decompiled the 'known to work well' driver for whatever chip!! There are probably a number of internal chip biases that need to be set roughly right. Maybe just a switch or chip bug that takes some sort of trick to initialize properly. Just my humble opinion :)).
