OK, and than it runs, but we do know nothing about the reasons :D

Well, remember.
There are two other problems for me, which I could not explain.

It seems there is a bottleneck and I think the reason therefor are not 
proper settings for the CPU.

BC_XMAP_1 is set to 0x60

a look to the datasheets says that therefore are not much things 
enabled. I guess there is a whole piece of memory not writeable, more 
not useable.

ok first.

after filo has load the kernel and the initrd, there is a jump and the 
kernel is uncompressing. I'm not sure, but one of them needs more time 
as it should, also I think this is done somewhere in the memory.

my system boots readonly, but I don't know why
means VFS: booting bla,bla readonly

For me the whole stuff is running out of the ram
It could be that unuseable memory segments are needed for that.
