Hello
Regarding dirk issues with power, I think he just can't power off the module ie it's always draining the battery. but it eats so little power than it should be neglibigle. If you use a WML AHR C09, you will not have that problem as it'll work just like in a standard Zaurus.
For your friend, I suggest soldering a WML AHR C09 by wires. If you want to do it cheap, a Billionton module like the one used by AlbertR should be fine. I've purchased some and I'm testing them. I'll be happy to offer you one if you want, but I'd suggest you the WML AHR C09, if only for the power issues and my experience with it on the simpad (works like a charm! associates to cellphone, keyboards etc)
BTW, I finally started working on the dead 6000L I was offered. It is dead as can be. The motherboard sustained power damages IMHO, ie I can't test the memory upgrades I'll be doing and I've had no news from bfgh regarding the chip purchases.
Anyway, it's a first step. I'll try to purchase a 6000 with a broken screen for the motherboard.
