I'am using ELDK 4.2, 2.6.34 linux with config files for my ppc460gt custom board and RFSB from git for ramdisk generation
kernel image is running with - ramdisk_size=32768 root=/dev/ram rw console=ttyS2,115200
and ramdisk size is also 32768
=> bootm 400000
WARNING: bootm_low + bootm_size exceed eff. memory
