Ah, it works fine with linux-2.6.19 (it was trivial to crosscompile). So it
seems the names of the patches are just wrong.

I still fail to mount the root fs via NFS (tcpdump reports no network
transfer after loading the kernel) and to have root on a local hard disk:
[17179594.972000] XFS: file system using version 1 directory format
[17179595.044000] XFS: SB validate failed
[17179595.092000] VFS: Cannot open root device "sdb8" or unknown-block(8,24)
[17179595.172000] Please append a correct "root=" boot option
[17179595.240000] Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(8,24)

I need to check this "SB validation". But I'm sure I'm able to embed an
initrd into the kernel as this works already with the old Gentoo kernel.
