Is it true that the kernel has problems on machines/architectures where
main memory isn't contiguous ? That would be quite a downer for my plans to
build a Linux-running StrongARM board, as the DRAM banks on a SA-1100 have
pretty large holes in between (in physical address space).

to run on them, that is]
