Thanks for the hint.
You could be right that the shadowram isn't setup right.
But if i'm not mistaken the original malloc_low range (the "9-segment")
is below shadow ram in conventional memory?

In the past years i looked several times at those geodelink msr range
setups, it's quite complicatedand and there were several problems.
Also there are lots of different memory regions (with different cache
setup?) in coreboot and SeaBIOS and i would have liked a table with
memory range prerequisites but i couldn't find one.
I'l look at it some more in the next days.

Thanks, Nils.
