Sorry about the quoting.  I'm not used to using a mailing list such as this
one.

I have a feeling that the issue may relate to a certain type of clock
configuration (ie only when certain dividers are used) or some silicon
release.  All i know is that my board dies if i write in one step.

I'm not sure as to whether linux boots properly yet - the console output is
garbled by what seems to be an incorrect baud rate somewhere.  As this is
being derived from the ~60Mhz master clock I am using, i think i need to fix
this problem in the kernel :(
