I have used the linuxppc development env. with 2.2.12 kernel, the process can only map to the logical address between 0x0 - 0x80000000. But under the redhat (kernel 2.2.5, x86), I can map to 0x0 - 0xC0000000!!!
Is the 2.4.x ppc kernel also have the limit?

You can change this on newer kernels (its a config option,
CONFIG_TASK_SIZE). Eg on my titanium powerbook running 2.4.20-pre4:
# cat /proc/self/maps
...
bfffe000-c0000000 rwxp fffff000 00:00 0
