This still breaks under Debian sarge. There is this (german) forum
thread about it:
http://www.debianforum.de/forum/viewtopic.php?p=570102
Robotic english translation:
http://translate.google.com/translate?u=http%3A%2F%2Fwww.debianforum.de%2Fforum%2Fviewtopic.php%3Fp%3D569756%26sid%3D20278bfd231c5dac45fa0f2763c7ec54%23569756&langpair=de%7Cen&hl=en&ie=UTF-8
And it indicates that 0x510 would be the better offset due to 0x600
making it clash with the data section beneath. Indeed when I change it
to 0x510 I can compile the kernel with binutils 2.15-6.
I'm hoping this wont cause the kernel to eat my grandma. :)
