After having given up with GCC some weeks ago I came across

and later

As far as I understood, the previous versions allowed to write code
for the new chips and allow you accessing the upper flash memory
with some low level LPM fiddling, but they do not provide executable
code above 128kB. But I'm no regular reader of the mailing list too.

I seldom use JTAG ICE debugging. IMHO, single stepping is a waste
of time, which could be better used for thinking about the code.
But here is an exception. Without JTAG ICE you are probably lost.
