I have the same problems and I have got dmesg log.
My bug seems to be related to a bug that exists also on 2.6.3x kernels on amd64 and on 3.0.0 kernels (but here it does not hang the whole machine).
I'll test your workaround about the SIM card to see if it's related or not and then act on consequence.
