Thanks for the information.

Unfortunately I had to link my kernel to an other address 
(0xe000007000000000) because I don't have physical memory there.
See my memmap output below!

Now the loader can load the kernel, but on jumping in the kernel-code I still get an MCA:

/boot/kernel/kernel data=0x87448e+0x1c36d2 syms=[0x8+0x73938+0x8+0x68109]
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel] in 8 seconds...

Type '?' for a list of commands, 'help' for more detailed help.
OK boot -v
Entering /boot/kernel/kernel at 0xe000007000068000...
POD entered via MCA, using Cac mode

Anything I could have missed in your instructions?
(The only difference is that I double-quote dt:sgisn!)
What other information shall I provide?
