Topi,
I don't know what you're nfs problems are.
initrd is broken. In the 2.4.0-test kernel (and probably others), some
necessary lines were removed from arch/ppc/boot/head.S. I believe they have
been added back in the more recent source. Here is a patch:

Also, the sandpoint_setup_arch() routine in arch/ppc/kernel/sandpoint_setup.c
needs to be fixed. Change the SCSI_CDROM_MAJOR to RAMDISK_MAJOR.
These hacks should get your ramdisk going...
