Because the hardware I am running on (Netgear WGT634U) is only supported
on kamakaze that is what I have been running for a round a month. It is
actually quite stable, and using a 2.6.15 kernel. For the 634u I did not need
a JTAG cable, just as serial cable which then gives boot access to the "BIOS"
which should allow me to recover from most problem as I can ftp in a new
image from that command line.
