Actually, cross-building on NFS does tend to find a _lot_ of issues
which crop up with board ports; especially PCI arbitration, DMA
coherency, cache and MMU issues. LTP often doesn't catch the same
problems.

I agree that it's not so easy on a board with 32Mb of RAM, since that's
only 4,000,000 bytes -- but 32MiB ought to be _perfectly_ sufficient :)
