Thank you for sending me your posting as CC. I subscribed this mailing
list but I don't receive all postings. I am not sure what the problem is.
Of course it could be my ISP.

Another problem is my webinterface for email. Using this I can't send
posting to correct position in mailing list. So please look at mailing
list archive to see all my postings about my problem.

Why do you think I use different kernels? Both bootloaders get
/boot/vmlinuz as kernel parameter. So that should be the same.

I want to remove my original BIOS and use coreboot to speed up booting.
Therefore I don't want to change my kernel. I hope to use my system like
without coreboot (maybe late I will optimise my linux system).

I think there are same parameters but I will look at them again (maybe a
little difference?). But I can test only on monday because of my job. So I
can't give you that information now.

I will look at this too. But in some others postings it could be a problem
with missing DMI or some strainge errors by using PCI in filo. That would
be my next tests.

Thank you for help. I will send you my results as CC too. So my email
problems should not be a problem for you.
