No phys_to_virt() should already take care of that:

static inline void * phys_to_virt(unsigned long address)
{
       return (void *)(address + PAGE_OFFSET - PHYS_OFFSET);
}

Does your platform code do some address translation by using
CPHYSADDR() macro or by using anything else than pa() ?

2.6.20 should be OK. This patchset need some commits which have been
applied before.

yes, please, it may help. Can you send your config file as well ?

Just to be sure, is your PAGE_OFFSET equal to 0x80000000 ?

Thanks
